A balance of instrumental and vocal tracks, the compilation is a terrific starting point for exploring the artistic and stylistic diversity in modern slack key. Instruments on this album include everything from traditional mouth bow, 'ukulele, and percussion stones to 12-string slack key and modern acoustic guitars. Elder statesman Ray Kane lullabies us with his simple instrumental "Popoki Slack Key" (popoki means "little cat"); renowned improviser Cyril Pahinui and Sol Hoopii-influenced Bob Brozman combine 12-string slack key and acoustic steel guitar interpreting "Hilo E" and "Lili'u E" in a style evocative of the 1920s. Showing off how slack key works solo, in duets, or with mixed accompaniment, this is one of the most beautiful slack key compilations out there. --Erik Macki
