When GNR bad ass Slash was recording his solo record back in 2010 he collaborated with a superstar list of incredible musicians. Chester Bennington and Slash recorded a song called Crazy that, until now, had been unheard. For whatever reason Linkin Park pumped the brakes on having this song released at the time so Slash re-recorded the song with Lemmy Kilmister from Motorhead and called it Doctor Alibi.
This is only a 60 second clip but it is incredible to hear the voice of such an missed singer. If you're not an owner of Slash's solo record Slash, it is a must buy as it includes Ozzy, Iggy Pop, M. Shadows and Chris Cornell to name a few!
