Musically, Witchcraft is pretty good. They've 'explored' all sorts of retro sounds whether it be Zeppelin through to The Doors.
However, the vocals kill it. Yes, I'm picky, and if I find something on an album that just gets in the way I can usually let it go. But does every single line on the entire album have to be sung through that voicebox emulator thingy?
I mean, they took something relatively decent and just ruined it IMO. That's the frustration I feel because it prevents me from listening to it.
