The Apples in Stereo are an American indie rock band associated with Elephant 6 Collective, a group of bands also including Neutral Milk Hotel, The Olivia Tremor Control, Elf Power, of Montreal, and Circulatory System. 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 and Eric Allen, as well as more recent members John Dufilho, John Ferguson, and Ben Phelan.
The band's sound draws 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, bubblegum pop, power pop, punk, electro-pop and experimental music.
The band is also well known for their appearance in a The Powerpuff Girls music video performing the song "Signal in the Sky". It aired immediately after the show's seventh episode of season 4, "Superfriends", which was based on the song's lyrics.
