Bill Campbell is a fingerstyle guitarist whose specialty is Hawaiian slack key guitar instrumentals. He is an accomplished musician who plays several instruments, including guitar, piano, piano accordion, and saxophone. He began taking accordion lessons at the age of 8, played the saxophone in high school and U.S. Army bands, and has played the guitar for as long as he can remember. He has concentrated on slack key, or ki ho'alu, guitar, exclusively since the winter of 1996, when he began to spend winters on the island of Kauai, where he developed his fascination for this genre of guitar music. He has taught private guitar and piano lessons, and he has performed with groups and as a solo performer in his native state of Virginia and in Hawaii. His first CD, 'Kauai On My Mind', is his tribute to both the island where he learned to love this music and to his teacher there, slack key guitar master Hal Kinnaman.

Bill has used the simplicity of the slack key tunings to make his own arrangements of over 300 songs, many of which are not considered to be either Hawaiian or slack key, such as 'September Song' and 'Green Eyes' (both on his 'Kauai On My Mind' CD), 'Siboney', and Enya's 'Marble Halls', but which are played in the slack key style.
