After a seven-year hiatus, Karma To Burn is back and spent all of last year burning through the U.S. and Europe to let everyone know it. Now after dropping their newest album, Appalachian Incantation, this instrumentals-only metal band is headed out on tour once again. Their new album, although it contains two songs with guest vocalists, is still full of the intense guitar riffs and pulse-pounding rhythms KTB fans love. Karma To Burn will be playing at Brooklyn’s Knitting Factory on May 14 with Year Long Disaster, Naam and Elks. $12-$14.
