Lawrence Casserley (born Essex, England, 1941) is celebrating fifty years of making electronic music. He has devoted his career to the creation and promotion of live performance electronic music in a wide variety of ways. He has worked with many of the leading improvisers, particularly Evan Parker and his Electracoustic Ensemble. Casserley’s instrumental approach to live computer sound processing is the hallmark of his work, which is documented on many CDs, and he has performed and given workshops throughout Europe and in North and South America, Asia and Japan.
