When you think of bands that would collaborate with Pearl Jam, Incubus might not be the first to come to mind. But Pearl Jam’s new album will feature Incubus guitarist Mike Einziger. In the early hours of Wednesday morning, Einziger tweeted from Los Angeles, saying he was with the band recording strings for their upcoming album. He posted a photo and wrote, “In the studio with my girl and Eddie Vedder, recording strings for Pearl Jam’s new album.”

Pearl Jam formed back in 1990 and grew up as a part of the Seattle grunge music scene that gained popularity in the ‘90s. The band’s 1991 debut, Ten, has now sold 10 million copies in the U.S. Popularly acclaimed by both general audiences and music critics alike, the band was nothing if not influential.

Last month, Pearl Jam guitarist Mike McCready told Rolling Stone that the band has been busy working on the follow-up to 2009’s Backspacer and already has seven songs “relatively completed.” They plan to finish the album “this year, for sure.”

**UPDATE** Pearl Jam’s representatives have recently released a statement saying that Einziger is NOT playing on the album. Einziger was present at the recording sessions because his girlfriend is playing strings on the album, according to the band’s rep.
