The concept of duality has been a defining characteristic of guitarist Nels Cline since he first emerged in the late 1970s.  On one hand, there's the harmonically sophisticated, compositionally rich Nels Cline who contributed to jazz recordings by everyone from Tim Berne to Vinny Golia to Julius Hemphill. On the other, there's the more extreme, visceral Nels Cline, who brought unbridled power and reckless abandon to the post-punk, alternative rock of Mike Watt, Thurston Moore, and The Geraldine Fibbers. These days Cline continues to explore this dichotomy, whether it's in his role as lead guitarist for famed rockers Wilco or with The Nels Cline Singers, his flagship group for the last ten years. The Singers' fourth release and Cline's seventh as a leader for Cryptogramophone, approaches the concept of Yin and Yang with a series of firsts for both the group and its intrepid leader, slyly dubbed by Jazz Times as "The World's Most Dangerous Guitarist."

Initiate, in a beautifully designed, six-panel digipak featuring Simon Norfolk's gorgeous photographs of the world's largest machine (the Large Hadron Collider at CERN) is Cline's first double album and, with its second disc culled from a September 2009 performance at Cafe du Nord in San Francisco, the Singers' first live album.
