Leonard Kwan (1931-2000) was one of the most influential Hawaiian slack-key guitarists to emerge in the period immediately preceding the Hawaiian Cultural Renaissance of the 1970s. He made the first LP of slack key instrumentals, co-wrote the second slack key instruction book, and composed a number of pieces that have become part of the standard repertory. Most players will include Kwan, along with Gabby Pahinui, Sonny Chillingworth, and Atta Isaacs, on a list of the most significant players of the older generation.
