For my money the best rhythm guitarist in history. Angus often said that Malcolm could fill in for him anytime, but that nobody can play rhythm like Malcolm.

Critics still put Keith Richards at the top of the rhythm list...Richards hasn't played decent rhythm since Exile on Main St. Richards is a rock star...fucking around on stage like a rock star for your rock star worshipping pleasure since 1972.
