Answer the question at the end by quoting:

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.
In late 1991, Robert Schneider met Jim McIntyre on a commuter bus in Denver, Colorado. Schneider had recently moved to Colorado from Ruston, Louisiana, and often initiated conversations with McIntyre. When Schneider asked McIntyre what his music interests were, McIntyre named his favorite band: The Beach Boys -- a band Schneider was particularly fond of. Realizing that they shared many musical interests, McIntyre introduced Schneider to Hilarie Sidney. McIntyre already had a band called Von Hemmling in which McIntyre played bass and Sidney played drums. With Schneider, they discussed the idea of starting a band and perhaps a recording label. Schneider later met Chris Parfitt, who was also already in a band at the time that Schneider unsuccessfully auditioned for on bass. Schneider and Parfitt also became friends, however, and toyed with the idea of having a rock band similar to The Velvet Underground or Black Sabbath, with production qualities similar to that of The Beach Boys.  Schneider then spent two weeks in Athens, Georgia recording music and spending time with his childhood friends Will Cullen Hart, Bill Doss and Jeff Mangum. He discussed the idea of starting a record label with them (which soon became The Elephant 6 Recording Company). It was also at this time that the name "The Apples" came about, inspired by the Pink Floyd song "Apples and Oranges".  The earliest incarnation of the band began to form in 1992 upon Schneider's return to Denver, first between Schneider and Parfitt, both of whom played guitar. The two recruited McIntyre and Sidney during the autumn of that year, practicing material through the winter. Their first few live shows took place the following January, many of which were with the band Felt Pilotes. From February to April 1993, the band recorded their debut 7" EP, Tidal Wave, and released it in June as the first record ever to bear the Elephant 6 logo.

IN: Saosin is an American post-hardcore band from Orange County, California, United States. The band was formed in 2003 and recorded its first EP, Translating the Name, that same year original vocalist Anthony Green left Saosin due to personal reasons. In 2004, Cove Reber replaced Green as vocalist after auditioning for the role. The group recorded its self titled debut album which was released on Capitol Records on September 26, 2006.

The original lineup for Saosin, consisting of Burchell, Shekoski, Kennedy and Green, was formed in the summer of 2003. On June 17, the band released their first commercial production, the EP Translating the Name. It was an immediate success and was immensely popular on online forums and music sites. Saosin first became popular through promotion and exposure through the Internet. They became known for their distinct musical styles long before their first studio-length album was released, and were popularized on social networking and music sites such as MySpace. The E.P. has sold an estimated 62,000 copies.  Bassist Zach Kennedy left the band early on, as he wanted to pursue a career in art. He was later replaced by Chris Sorenson. A local Southern Califonian drummer by the name of Pat Magrath,  was hired only for the recording for the EP, according to Burchell. The band was impressed with his drumming skills however, and he later appeared as a guest performing Lost Symphonies live with the band. Alex Rodriguez was unable to record Translating the Name as he had promised his band at the time Open Hand he would finish recording with them. Danny King filled in for live drums with the band before Rodriguez completed his responsibilities with Open Hand and joined Saosin full-time after the EP release. Saosin went on a U.S. tour with bands Boys Night Out and Anatomy of a Ghost shortly after the release of Translating the Name.  In February 2004, the band's vocalist Anthony Green left Saosin and later formed the band Circa Survive. Green was homesick, depressed and said he was missing his family. Green was also disenchanted with the direction of Saosin and disliked that the band excluded him from the writing process. The band finished their Warped Tour obligations with Story of the Year's Philip Sneed taking the mic. A public, nationwide audition then took place.

Did anyone join them during this time?
