Alex Cline (born January 4, 1956) is an American jazz drummer.
Born in Los Angeles, California, Cline began playing drums with his twin brother, guitarist Nels Cline, at the age of 11. Their first band was called Homogenized Goo and included David Hirschman on guitar. Alex Cline began a musical association with woodwind artist Jamil Shabaka in 1976 as "Duo Infinity". In 1977, he became a member of Vinny Golia's group as well as the Julius Hemphill Trio (along with Baikida Carroll), formed the electric improvisational trio Spiral (with brother Nels and synthesizer player and multi-instrumentalist Brian Horner) and began performing solo percussion concerts.
In 1979, Alex and Nels Cline, along with bassist Eric von Essen and violinist Jeff Gauthier, formed "Quartet Music", a group that enjoyed continued success in its performances and four recordings over an eleven-year period and was awarded grants from the National Endowment for the Arts and the California Arts Council.
In 1982, Alex Cline made his solo debut with Not Alone (Nine Winds), a double LP of percussion music. In 1987, he recorded The Lamp and The Star (ECM), his first album as a bandleader-composer. As the leader of his own group, The Alex Cline Ensemble, he can be heard on Sparks Fly Upward and The Constant Flame, two releases on Cryptogramophone Records, an LA-based independent creative-jazz label. Cline’s other improvisational collaborations include right of violet and The Other Shore, both with Jeff Gauthier and ex-Shadowfax guitarist G.E. Stinson, and Cloud Plate (Cryptogramophone) with Stinson, vocalist Kaoru and koto player Miya Masaoka.
