Last year, Josh Bolof, the local producer who goes by Stres, created a sad-sack, sleigh bell-ringing Christmas carol called "Nothing Feels Like Home Anymore." This year, he's back representing those of us who feel that the holidays are sort of a depressing drag. ("Once again it's the Holiday season," he wrote me in an email, "and once again, I wrote a sad Christmas song.") Bolof's holiday composition this year is a collaboration with Erik Foster of the Dirty Sidewalks. "Christmas Is Here (You're Still Gone)," says Bolof, is "dedicated to the spirit of being alone on the most jolliest time of the year." It is a contemplative and solemnly beautiful track built around a vocal sample from Sister Irene O'Connor, an Australian nun who released a spiritually psychedelic album in 1976 called Fire of God's Love/Songs to Ignite The Spirit. The sample, from O'Connor's song "Fire," is a genius find.
