Oooh, totally agree with you on the Current 93 front...i really like the music, but his pityful efforts at fey squawking really are like chalk on a blackboard to my ears.
Mind you, on a slightly different tack, much as i adore The Heads, and i don't mind their vocals at all, i do wish they would write decent lyrics, they are pretty dire...they'd do better as an instrumental group i think.
