... or at least restore some integrity.

Rolling stones and other aging stadium rock acts : Low key acoustic sets at small venues paying tributes to the artists who inspired them (Muddy Waters etc.)

Boyz II Men and other R&B singers/groups : an album of metal ballads done smooth R&B style. (Guns and Roses Cry/Patience, ZZtop - rough man, Every rose has its thorn etc.)

Who would you fix up and how?
