Alphonso Johnson:

After a short stint on trombone, Alphonso Johnson took up the electric bass in 1968. His early gigs included time with Horace Silver, Woody Herman (1972), Chuck Mangione (1973), and Chet Baker. Johnson rose to fame while touring and recording three albums with Weather Report (1974-1976). This was followed by stints with Billy Cobham (1976-1977), Flora Purim, and the Crusaders. Johnson's funky lines on electric bass have been quite influential and in great demand ever since, both in the studios and in the fusion/funk world. ~ Scott Yanow, All Music Guide
