If you've never heard Blind Willie Johnson, you are in for one of the great, bone-chilling treats in music. Johnson played slide guitar and sang in a rasping, false bass that could freeze the blood. But no bluesman was he; this was gospel music of the highest order, full of emotion and heartfelt commitment. Of all the guitar-playing evangelists, Blind Willie Johnson may have been the very best. Though not related by bloodlines to Robert Johnson, comparisons in the emotional commitment of both men cannot be helped. This two-CD anthology collects everything known to exist, and that's a lot of stark, harrowing, emotional commitment no matter how you slice it. Not for the faint of heart, but hey, the good stuff never is.
