Laura MusselmanDuff McKagan at Sunday’s Hootenanny for Haiti at Showbox at the Market. McKagan’s column runs every Thursday on Reverb. He writes about what music is circulating through his space every Monday. More Hoot photos after the jump.I’m sitting here backstage with Mark Pickerel at the Hootenanny for Haiti benefit, Sunday night at the Showbox at the Market. This gig includes many great cover songs that I either haven’t heard for a long time, or never before. Check it out:”Even The Losers,” Tom Petty: This song had a profound effect on Mark as a kid and he somehow seemed to feel Petty’s pain even back then. For me, it is just simply a great song, timeless and passionate.”Love Hurts,” the Graham Parsons version: Star Anna and Mark have been looking for an excuse to sing a song together for a few years. Tonight was a truly great experience for me as a musician, to see others excel at what they do. If you haven’t checked out Mark or Star, well it’s never too late.”Crown of Thorns,” Mother Love Bone: Sean Smith and Stone played this song tonight…KILLER! Sean Smith is fucking a God-like singer and should be worshiped!Mark Pickerel, Duff McKagan, and Mike McCreadyKim VirantKim WarnickPearl Jam’s Mike McCready
