A lot of the bands that came out of the Seattle "grunge" scene were close.  But, perhaps the closest connection was between Soundgarden's Chris Cornell and the members of Pearl Jam.

Prior to Pearl Jam, guitarist Stone Gossard and bassist Jeff Ament were members of a band called Mother Love Bone.  Their singer, Andrew Wood, was Chris Cornell's roommate.  Wood died of a drug overdose on March 19, 1990.

After Wood's death, Cornell wrote a few songs about his friend.  He shared the songs with Gossard and Ament who were in the middle of starting their new band, Pearl Jam.  The trio recorded with Soundgarden (and future Pearl Jam) drummer Matt Cameron along with Pearl Jam guitarist Mike McCready.  Eddie Vedder contributed vocals to Hunger Strike shortly after joining Pearl Jam.

The grunge supergroup released one album with the name "Temple of the Dog."

On Monday night, Cornell will kick off "Pearl Jam Week" on Late Night with Jimmy Fallon.  He will perform Footsteps with The Avett Brothers.

Watch Cornell discuss his relationship with Pearl Jam and the significance of Footsteps.
