the University of Michigan, co-founded StarKid Productions, a musical theater company. His most prominent acting role with StarKid has been that of Harry Potter in the musical comedies A Very Potter Musical, A Very Potter Sequel, and A Very Potter Senior Year (based on the Harry Potter series of novels by J.K. Rowling). Criss is credited as one of the primary songwriters and composers for StarKid Productions. He has contributed songs to A Very Potter Musical, Me and My Dick (which became the first-ever student-produced college musical to reach Billboard, debuting at No. 11 on the Top Cast Albums chart), Little White Lie, and A Very Potter Senior Year. Subsequently, Criss solely composed all the songs and music for A Very Potter Sequel, its companion album A Very StarKid Album, and Starship, which landed at No. 1 on the Billboard Top Cast Albums chart, and at No. 134 on the Billboard 200 chart. 2010–2015: Breakthrough with Glee Glee Criss portrayed Blaine Anderson, on the Fox television series Glee. He made his first appearance in season two in the episode "Never Been Kissed", which aired on November 9, 2010. Blaine attended Dalton Academy and was lead singer of its glee club, The Dalton Academy Warblers. His first performance, "Teenage Dream" by Katy Perry, was featured on the soundtrack album Glee: The Music, Volume 4. It reached number eight on the Billboard Hot 100 in the week ending November 27, 2010, and number one on the Billboard Digital Songs chart. It was the best-selling song in the US that week, selling 214,000 copies, the largest figure for a Glee title. It was only the second US-certified gold single in the show's history. Both Billboard Jillian Mapes and Erica Futterman of Rolling Stone deemed "Teenage Dream" the best song of "Never Been Kissed", the episode in which it featured. The New York Daily News Anthony Benigno gave the song an "A", and noted that it was "flawless" and improved on Perry's original. The performance was nominated for the Best Gay Moment of the Year and Favorite Music Video awards at the 2010 AfterElton.com Visibility Awards. A Billboard cover-feature on Criss noted that the performance "arguably ushered in the trend of more current pop hits being reworked by the [Glee] cast." Later songs performed by Blaine and the Warblers became popular enough to warrant a Warbler soundtrack album, Glee: The Music Presents the Warblers.
