Lonnie Mack, April 18, 1977, Boarding House, San Francisco. American blues singer and guitarist. In the early 1960s, he recorded several full-length electric guitar instrumentals which combined blues stylism with fast-picking techniques and a rock 'n' roll beat, the best-known of which are "Memphis", "Wham!", "Chicken Pickin'" and "Suzie-Q". Mack's fiery instrumentals from this period set a new standard of virtuosity for a generation of rock guitarists and formed the leading edge of the "blues-rock" guitar genre.
