Ben Harper first bonded with the members of Pearl Jam when the grunge-legends took him out on the road for a European tour back in the 1990s. Since then Harper has played with the members of Pearl Jam numerous times, most recently on Sunday when he joined Eddie Vedder for a few songs at Los Angeles’ Wiltern Theatre. Partway through Vedders solo set, Harper took the stage to duet with the Pearl Jam singer on ‘No More,’ a track the pair recorded for the politically-charged Body of War soundtrack. In addition, former Pearl Jam/Red Hot Chili Peppers drummer Jack Iron, who introduced Vedder to his future bandmates after their previous band Mother Love Bone dissolved, appeared on Pearl Jams hit cover of ‘Last Kiss’ and jammed with both Vetter and Harper on All Along the Watchtower.’ Harper and Vedder performed both No Moore and Rocking in the Free World together at Lollapalooza last August Since leaving the alt-rock world, Irons has focused primarily on more improvisational music.

Vedder will appear at San Diego, CAs Spreckels Theatre tonight and tomorrow.
