Query: Jan plays the blues

This album features Jan Akkerman and Curtis Knight (who sadly died recently) playing the blues. Curtis Knight made his name in the 1960's and featured a guitarist by the name of Jimi Hendrix in his band. This album features a number of Jimi's songs and covers (including Little wing and All along the watchtower) and in keeping with the tradition of the blues this record is raw with some fierce blues playing from Akkerman and soulful vocals from Knight.As for previous comments about Jan Akkerman never being in a vocal band check out his early work with The Hunters and his pre-Focus hard rock band Brainbox.
