Screaming Bloody Murder Tour

The tour began on April 17, 2010, dubbed as the European In Your Pants Tour, the band played a series of festivals and some headlining dates in April 2010, with plans to follow in May–June 2010 including appearances in Rock am Ring, Rock im Park and Nova Rock, which were all canceled upon drummer Steve Jocz' involvement in a car accident. After Stevo's recovery, the band started their North American leg on June 25, 2010, and toured as part of the Vans Warped Tour 2010 in the US and Canada, though they canceled few of the dates in the Warped Tour to take part at the Japanese Summer Sonic Festival on August 7 & 8, 2010. Upon Deryck being hospitalized for a slipped disc in his back after he was attacked at a bar in Japan, the band had to cancel the five remaining Warped Tour dates they had to play in August upon returning from Japan. The band continued their European tour on August 31, 2010, with a series of rescheduled dates of the summer European In Your Pants Tour until September 12. Following this, the band embarked on headlining European tour between October 27–December 1, 2010, headlining the annual Eastpak Antidote Tour, with support from The Black Pacific, Riverboat Gamblers and Veara, being the band's longest and most extended tour in Europe. During the tour, the band debuted a new song, "Skumfuk", the first song to be released from Screaming Bloody Murder, which was leaked to the internet earlier in July 2010.

On February 4, 2011, the band went on another European leg, dubbed as the first official European tour in support of Screaming Bloody Murder, which was announced for release on March 29, 2011. On this leg, the band played a total of 13 dates in mostly small venues, almost all of them sold out, and debuted the single "Screaming Bloody Murder" live for the first time. On February 16, 2010, the band began touring Australia as part of the Soundwave Festival dates through February–March 2011. After playing two dates in Brisbane and Sydney, it was announced on February 28, that Deryck was hospitalized with severe pneumonia and the band will be cancelling the rest of their Australian tour.[1][2] In March 2011, the band celebrated the release of the Screaming Bloody Murder album in a short set of 8 shows in the US, including two homeland dates in Canada. The album's release show took place at the Glass House in Pomona, California.

In May 2011, the headlined a tour in Japan, dubbed as the 10th Anniversary Japanese Tour 2011. The tour's shows were the first where the band debuted new songs from the new album Screaming Bloody Murder except "Skumfuk" and the title track, which the band were already playing for a few months now. During the tour, the band was also the first international act to play in Sendai after the 2011 Tōhoku earthquake and tsunami. In the summer of 2011, the band embarked on a European summer leg, mostly playing European festivals such as Hurricane, Southside and Sonisphere Festival, also visiting for the first time such countries as Hungary, Slovakia, Croatia and Ukraine. In August 2011, the band was set to perform two shows in South Africa, the band's first shows in Africa ever, though the first show in Durban on August 5 was cancelled 2 hours after the band was set to take the stage, following severe strong winds rendered the stage area unsafe.[3] The second South African show at the Oppikoppi Festival on August 7 took place as planned and was also streamed online via Ustream.

Following the South African dates, the band was set to return to North America playing a small bunch of Canadian shows as well as 5 Warped Tour dates, making up for the cancelled dates from last year's Warped Tour, though 3 dates into the tour, on August 13, 2011, it was announced that Deryck has re-injured his back and the band was forced to cancel once again the 2 remaining Warped Tour dates, as well as 4 Canadian dates.[4] In early September 2011, the band was set to go on their first ever Latin American tour, where they were supposed to visit for the first time Mexico, Brazil, Chile and Argentina. In late September, the band was set to return to Australia, playing the new Soundwave Revolution Festival dates, making up for the cancelled Australian dates in February, though on August 9, 2011, it was announced that the Soundwave Revolution Festival would be cancelled[5][6] following headliners Van Halen pulling out and the organizers failing to close a deal with a second headlining band to appear on the festival, later confirmed to be Aerosmith.[7]

On August 23, 2011, it was announced on the band's official website that following Deryck Whibley's back injury on August 13, which forced the back to already cancel their US and Canadian dates in August, the band would be indefinitely postponing all upcoming tour dates for 2011, due to Deryck undergoing a treatment for his medical condition. It was confirmed that the band's first ever South American tour as well as their first ever Asian tour (excluding Japan), would all be cancelled, and rescheduled for some time in 2012.[1]

On September 28, 2011, the first dates of the rescheduled 2012 Screaming Bloody Murder Tour were announced, these being a series of 11 dates in the UK and Ireland, co-headlining with New Found Glory, in February 2012.[8] On November 1, 2011, it was announced that Sum 41 will co-headline the PunkSpring Festival in Japan, on March 31, 2012 in Tokyo and on April 1, 2012, in Osaka, with The Offspring, New Found Glory and All Time Low.[9] It was then announced that the PunkSpring performances will be followed by a rescheduled Asian tour making up for the cancelled dates in October 2011, visiting such countries as China, Taiwan, Indonesia and Singapore. Dates in Malaysia and the Philippines though were not rescheduled.[10]

On January 20, 2012, it was announced on the Kerrang website that Sum 41 was forced to pull off from the Kerrang UK tour in February, where they were supposed to co-headline with New Found Glory. It was said that frontman Deryck Whibley, who has suffered from a serious back injury back in August 2011, is still not well enough to play the tour, and so the band would be replaced by The Blackout.[11]

After finishing the rescheduled Asian leg of the tour in April 2012, there was no more information released from the band about further touring. After being asked, bassist Cone McCaslin has said that due to Deryck's back treatment it is unlikely that the band will be touring in the coming months, and most likely start touring again around the fall, though on May 23, 2012, the band has announced that they will be touring in the summer after all, announcing a few European festival dates, with more to follow throughout the months of July and August. During the summer European tour of 2012, the band played a long-than-usual set, playing many songs that were never played live, such as "Billy Spleen" and "Count Your Last Blessings", and songs that haven't been played in years, such as "A.N.I.C.", "Hyper-Insomnia-Para-Condrioid", "No Reason" and "Rhythms", with the setlist varying almost every night.

On September 10, 2012, the band announced their first full headlining North American tour in 4 years, being the Does This Look Infected? 10th Anniversary Tour, in which the band is set to play the whole Does This Look Infected? album, as well as their greatest hits and songs from Screaming Bloody Murder.[12]
