NSYNC in Concert

After completing a promotional tour for their debut album, the band announced their first tour in North America. Previously, the band toured Germany for their "For the Girl Tour" in 1997. The summer outing saw the band playing in nightclubs, state fairs and radio music festivals. After the airing of their Disney Channel concert special, “NSYNC: Live in Concert”, the band's popularity grew in the United States and additional dates were added to the tour. Now known as the "Second II None Tour", the band were now playing theatres and auditoriums. Before the tour began in November 1998, the band become the opening act for Janet Jackson's The Velvet Rope Tour during concerts in October 1998.[6]

The "Second II None Tour" leg ended in February 1999, after performing at a radio music festival in San Jose, California. Around this time, band member Lance Bass expressed the band would expand their upcoming tour to the United Kingdom. However, this did not come to fruition. The next leg of the tour, known as "Ain't No Stoppin' Us Now Tour" began in the spring of 1999. The band were now playing arenas in the United States. The tour was sponsored by Oxy Balance.[7] During an interview with the Hartford Courant, band member JC Chasez described the tour as:

"The concerts, yeah, are loud and crazy, and people scream and everything like that but it's fun. It's all in good fun. The core of the show is the same, the same old singing and dancing, NSYNC style: a high-energy, very personal performance".[8]

While performing a concert in New Haven, Connecticut, local radio station WKCI-FM declared March 13, 1999 as "NSYNC Day".[9] While touring in Florida, Bass became ill and missed the concerts in Tampa and Sunrise.[10] The tour was expanded once again to the summer, now called the "Boys of Summer Tour". The band were now playing amphitheatres and stadiums. The shows were sponsored by Clairol Herbal Essences.[11] For the August concert in Denver, the band allowed students of Columbine High School to attend the concert for free. During this time, the band was involved in a legal battle with their former manager Lou Pearlman and transitioning from RCA to Jive Records.[12] Towards the end of the leg, the band were forced to cancel concerts due to schedule conflicts relating to their lawsuit. The group made up the dates in their final tour expansion known as "The Winter Shows".[13] During an AOL chat in November with fans, Chasez stated the group was already planning for their next tour for their upcoming album in 2000.[14] He also expressed hoping to tour the United Kingdom, continental Europe, Australia and Japan. During The Winter Shows, the band performed their new singles, "Bye Bye Bye" and "Music of My Heart". The leg ended with a New Year's Eve concert in Honolulu.[15]

Music festivals and other miscellaneous performances

Cancellations and rescheduled shows

The band's performance at Disney's "Summer Jam" was filmed on May 12, 1999, and aired on ABC in June.[47] Their performances at "Summer Music Mania" and "Teenapolooza" were aired on UPN on August 31, 1999.[48] The July 2 performance at the National Car Rental Center was filmed was for a PPV special entitled, "'NSYNC 'N Concert". The concert was presented by WAM! America's Kidz Network and was made available on September 11, 1999.[67]

Overall, the tour received positive elucidation from music critics and concertgoers.[68][69][70] Gord Westmacott of the London Free Press wrote the boy band threw their female fans into a frenzy at the Centennial Hall in London, Ontario.[16] He continued: "All five returned to the stage for an a cappella medley of Bee Gees' songs, including 'Jive Talking' and 'How Deep Is Your Love', a move which seemed to win points with the parents and proved that yes, they really can sing. But it was the up-tempo material that drew the best response, as the members bounced around the stage in tightly choreographed dance routines, proving that they can dance too—or at least strut really well. And there was no question they knew exactly how to play the crowd, providing just enough pelvic thrusts amid the ernest and squeaky-clean production".[16]

Kieran Grant of the Toronto Sun enjoyed the performance at the Molson Amphitheatre. He said, "Imagine the fever pitch when their helmets were dropped to reveal heart-throbs JC, Justin, Joey, Chris, and Lance—NSYNC in the flesh. Of course, there was still a heavy layer of Gortex—gloves included—to come off as the track-suited NSYNC strutted about to tunes from their self-titled debut album. The group delighted their fans with their fluid and casual dance moves, hootin' and hollerin' and just-this-side-of-bad-boy posturing".[71] Mike Ross of Music Express called the performance at Skyreach Centre a "fusion of a rock 'n roll concert and a visit to Disneyland. He explained, "The crowd was on its feet—screaming, screaming, all that screaming ... There was actually something to scream about. Say what you want about boy-groups with millions of dollars in production at their disposal. They may be pinnacle of pop fluff, but they're not putting on boring concerts".[30]
