Incubus guitarist Mike Einziger is contributing to the new Pearl Jam album.  He tweeted the news with a picture of himself with his girlfriend and Pearl Jam singer Eddie Vedder.

Pearl Jam has been working on a follow-up to 2009's Backspacer.  In February, guitarist Stone Gossard said that the band was hoping to release the new album in the next "9 to 12 months."

Incubus is currently on hiatus.  Their front-man, Brandon Boyd, is looking to release a new album this summer.
