Hardworking trombonist Suavo J looks increasingly like a man on a mission to single-handedly rescue Memphis music, and he is everywhere these days, whether it’s playing with Otis Logan’s awesome 4 Soul aggregation, or the Crescent City-tinged Memphis-New Orleans Street Symphony band, or the more rootsy The Bones. The latter group was playing on Friday February 28 at the Center for Southern Folklore down on the Main Street Mall in downtown Memphis. The weather was cold, and there was only a modest crowd, but the band rocked the house for those of us who were there.
