Chris Cornell, who is best known as the frontman of Seattle grunge legends Soundgarden, died Wednesday night while on tour in Detroit, according to the AP. He was 52.

No cause of death is known at this time, but Cornell’s representative told the AP that the musician’s death was “sudden and unexpected.” AP News is reporting that police are investigating his death as a possible suicide, stating there were “basic things observed at the scene” to warrant this. Cornell had performed with Soundgarden in Detroit, MI, that night, and was later found dead on the bathroom floor at the MGM Grand Detroit hotel.

Fans of grunge should be delighted to learn that during its 20th anniversary year the excellent Temple Of The Dog album is available on MP3 as part of Amazon’s monthly $5 MP3 Album Deals.

Following the death of Mother Love Bone singer Andrew Wood, Soundgarden frontman Chris Cornell wanted to put together a tribute to his late friend. The roots of grunge behemoth Pearl Jam are here with Jeff Ament and Stone Gossard finally joining up with future Pearl Jam bandmates Eddie Veddar, Mike McCready and Soundgarden drummer Matt Cameron (who is now Pearl Jam’s drummer). The result was this: the eponymous album Temple Of The Dog.
