If you are only familiar with guitarist Nels Cline from the popular rock band Wilco, he's really a jazz musician who has been recording since the 80s. He's been a member of Wilco since 2004. He was born Jan. 4, 1956 in Los Angeles. Nels and his twin brother Alex are both musicians. Alex plays drums. By the time he graduated from high school, Nels was already a big part of the Los Angeles jazz scene. He first recorded in 1981 as part of Quartet Music with bassist Eric Von Essen. He was also a member of sax player Julius Hemphill's JAH Band. Cline first recorded as a leader in 1988. Then he formed the Nels Cline Trio in 1991. They recorded four albums in the 90s. He recorded again as a leader in 2000 and then he formed the Nels Cline Singers in 2002. Despite the name, the Nels Cline Singers are an instrumental jazz trio. I assume the name is a joke and also to distinguish it from his previous trio. This group recorded six albums. Canales' Cabeza is from the 2014 CD Macroscope on Mack Avenue Records. It's their latest CD. Musicians are Trevor Dunn on bass and Scott Amendola on drums. I don't think this band is together anymore. Cline's new band The Nels Cline 4 records for Blue Note. Their latest CD Currents, Constellations was released earlier this year. Cline still records and tours with Wilco. And he is active as a sideman. I don't know where he finds the time. But I know that Nels Cline is a great guitarist. Here's the Nels Cline Singers performing Canales' Cabeza. I think this is a series of short films produced to promote Macroscope.
