The Apples in Stereo, styled The Apples in stereo, are an American psychedelic pop and indie rock band associated with Elephant Six Collective, a group of bands also including Neutral Milk Hotel and The Olivia Tremor Control. The band is largely a product of lead vocalist/guitarist/producer Robert Schneider, who writes the majority of the band's music and lyrics. Currently, The Apples in Stereo also includes longstanding members John Hill (rhythm guitar) and Eric Allen (bass), as well as more recent members John Dufilho (drums), John Ferguson (keyboards), and touring member Ben Phelan (keyboards/guitar/trumpet). The band's sound draws strong comparisons to the psychedelic rock of The Beatles and The Beach Boys during the 1960s, as well as to bands such as Electric Light Orchestra and Pavement, and also draws from lo-fi, garage rock, new wave, R&B, power pop, punk, electro-pop and experimental music. The band is well known for their appearance in a The Powerpuff Girls music video performing the song "Signal in the Sky (Let's Go)". It aired immediately after the show's seventh episode of season 4, "Superfriends", which was based on the song's lyrics. Moreover, the band has appeared widely on television and film, including performances on The Colbert Report, Late Night with Conan O'Brien and Last Call with Carson Daly, guest hosting on MTV, song placements in numerous television shows, commercials and motion pictures, the performance of the single "Energy" by the contestants on American Idol, and a song recorded for children's show Yo Gabba Gabba.
