KCL, the iconic, genre-bending powerhouse trio led by visionary guitarist Wayne Krantz and featuring drummer Keith Carlock(Steely Dan, Sting, John Mayer) and bassist Tim Lefebvre (Tedeschi Trucks Band, David Bowie), held a Thursday-night residency at NYC’s 55 Bar throughout the first decade of the new millenium. Cutting live recordings from the club and posting them online in the early days of the internet and touring only sporadically, KCL developed a thoroughly original style of interactive group improvisation inspired in part by the great Miles Davis Quintet of the 60s, but played out in spontaneously generated contexts of heavy funk, rock and electronica instead of straight-ahead swing.
