We've been hearing about Slash's new solo album for a bit, but now we have an idea of what it will sound like, and the answer is "awesome." Slash isn't a singer, so he's bringing in some serious friggin' talent to help in that regard. On this Howlin Wolf song called "Killing Floor," Slash enlists the talents of AC/DC's Brian Johnson and I will admit, I never would have guessed that was Brian Johnson by the sound of it because it doesn't sound like he's vomiting up his vocal chords like he does on AC/DC songs. Don't get me wrong, I love AC/DC, but I truly has no idea Brian Johnson could just... sing. THEN he has Aerosmith's Steven Tyler in there as well, but- PLOT TWIST- Steven doesn't sing a note. Just rips it up on harmonica. This will go down as an all-time Howlin Wolf cover.
