From their website:
Formed in Osaka, Japan, in 2005 indigo jam unit consists of Yoshichika Tarue (piano), Katsuhiko Sasai (double bass) Isao Wasano (percussion & drums), and Takehiro Shimizu (drums). Indigo jam unit's full length releases as of April 2011 includes six full length CD albums, starting with "DEMONSTRATION" in 2006, all selling more than 10,000 copies each in Japan. Other releases include the 2009 "Vintage Black" collaboration with label mates Flexlife, and from the same year, "re:common from indigo jam unit", the band's remixes of some of hip hop star Common's songs behind his original voice tracks. Check out their full discography here.
indigo jam unit's unique sound truly rests on the combination of the four members. Tarue's melodic classical-latin-jazz piano up front intertwined with Sasai's solid and groove driven basslines, all standing on the explosive and versatile rhythm section formed by Shimizu and Wasano. Being devoted live musicians, indigo jam unit records all their work in single takes. No overdubs, no click tracks, minimum post processing, and what you hear on the recording is pretty much what happened in the studio during that particular take.
