Source-derived summary

Sleeping People is an instrumental rock band from San Diego, California that formed in early 2002. They first started playing live at the end of that year as a trio consisting of Joileah Concepcion (guitar), Kasey Boekholt (guitar) and Brandon Relf (drums), with bassist Kenseth Thibideau joining the group in 2003. In 2005, the band released their self-titled debut album through Temporary Residence records. Around that same time, guitarist Concepcion left the band due to relocation, and her friend Amber Coffman replaced her on guitar. With Coffman, the band wrote and recorded three tracks that appeared on their second album, Growing. In early 2007, Concepcion returned to her former position while Coffman departed to join the Dirty Projectors, and the original lineup resumed. The style of instrumental rock they play is sometimes referred to as math rock, which is characterized by complex, atypical rhythmic structures, stop/start dynamics and angular, dissonant riffs.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 4, 2026.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
