Answer by taking a quote from the following article:

The Apples in Stereo, styled as The Apples in stereo, are an American 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 Ben Phelan (keyboards/guitar/trumpet). 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.

Several conflicts would lead Parfitt to leave the band in early 1994. John Hill, a former bandmate of McIntyre's, would join the band as a rhythm guitarist while Schneider began to grow more comfortable playing lead guitar. It was also at this time that Schneider began to take stronger creative control of the band, shifting its sound from its stronger rock qualities to a spacier pop sound. The band started work on a debut full-length album, but it instead became Hypnotic Suggestion, a second EP. However, after SpinART Records offered to buy the band an 8-track in return for an album, new plans for an LP arose.  In mid-1994, after Hypnotic Suggestion, McIntyre would be the second to leave the band, due to a number of personal distresses as well as stylistic changes that arose with Parfitt's departure. Having great difficulty finding a new permanent bassist, the band would rotate a number of frequent bass contributors, including Jeff Mangum of Neutral Milk Hotel, Kurt Heasley of The Lilys, Kyle Jones, Joel Richardson, and Joel Evans. Jim McIntyre would also occasionally guest on bass. This continued to be the makeup of the band as they toured the country in late 1994, recording the first half of their new album in Glendora, California. In early 1995, the band finished the album, Fun Trick Noisemaker, at Kyle Jones's house (the birthplace of Schneider's Pet Sounds Studio).  Now with a full-length LP to support, the band began touring again. Eric Allen, whom the band had previously auditioned as a guitarist after the departure of Chris Parfitt, joined the band as a much welcomed permanent bassist. Late 1995, Schneider relocated Pet Sounds Studio to Jim McIntyre's house. McIntyre continued to be involved in the recording and engineering of the band's albums until the mid-2000s.  A significantly different band from the original 1992 four-piece, the official name of the band gradually became "The Apples in Stereo", with the "in stereo" usually somewhat under-emphasized, whether in lower-case or in parentheses. Schneider described this in an interview: "It's very clearcut, actually: we're The Apples, the music's in stereo. It's not actually the band name - it's a step back from it, a band name once removed. We're The Apples, in stereo. Kind of like a TV show, 'in stereo!' That always seemed to be a really big deal, that it was in stereo." McIntyre later remarked, "It's cool the name changed cause the Apples and the Apples in Stereo were really two different entities."

What year did the band start?
