How did Anberlin get discovered??

From Wikipedia: “Lead singer Stephen Christian met bassist Deon Rexroat while they were both in high school, and they formed a punk band called SaGoh 24/7. Drummer Sean Hutson and guitarist Joseph Milligan joined the group as well.[8][dead link] The band released two albums, Servants After God’s Own Heart (1999), and Then I Corrupt Youth (2001), both under Rescue Records. After the albums sold only 1,300 units, Hutson left the band to start a family, and Nathan Young was brought in as a replacement. Christian, Milligan and Rexroat began working on a side project, marking the beginning of the end for SaGoh 24/7. The side project’s sound transformed after a suggestion from Milligan to develop more of a rock sound for Anberlin. They used money left over from shows they had performed previously and teamed up with producer Matt Goldman to record five demos. The demos that were then posted on PureVolume (which was mp3.com at the time), sparked attention from record labels, both major and independent. However, with advice from friends including Chad Johnson, and Timmy McTague from Underoath, the band signed with Tooth & Nail Records.”
