Shortly prior to the 2011 event, Insomniac founder Pasquale Rotella announced that they would no longer co-produce Together as One, due to "various issues" surrounding Go Ventures' commitments to "safety, production quality and the overall value of our fans' experience."
[1] At the same time, Rotella announced that Insomniac would partner with the club promoter Giant to form a new, competing New Year's Eve event known as White Wonderland, a two-night festival which would be held at the Anaheim Convention Center on December 31, 2011 and January 1, 2012.
[1][2] Similarly to Montreal's Bal en Blanc festival and the Sensation White tour, the winter-themed event would require all of its attendees to wear white-colored clothing.
[4] The inaugural 2011–12 edition of White Wonderland was a two-night event, headlined by Benny Benassi, Dada Life, Paul Van Dyk, and Steve Angello of Swedish House Mafia.
[5] The 2012–13 edition would be reduced to a one-night event on New Year's Eve, and featured performances by Above & Beyond, Avicii, Bingo Players, Dash Berlin, Dannic, Ferry Corsten, Hardwell, Madeon, Sebastian Ingrosso, and Tritonal.
