This album is one of the most startling out there at the movement. Son of Dave (real name B. Darvil, according to the back of the album cover) plays harmonica and sings, but also takes up the space normally held by the rythm section, stamping grunting and humming to create a brilliantly hypnotic backing. This isn't hip-hop style human beatbox, but a really inventive accompaniment. The songs reveal Son of Dave influences: there are some great blues covers, Rollin' and Tumblin', Mannish Boy, and a particularly a superb interpretation of Crossroad Blues. San Francisco is a relaxing change of pace, and he's joined by Martina Topley Bird for the excellent Devil Take My Soul. The great thing about this album is the combination of old and new styles. Truly fantastic listening.
