Touring bands will invade The Block on Dec. 17 for a stacked showcase. Memphis synth-rockers The Deathless will release their new 7-inch Through the Dark House at the show, alongside a cover set from masked experimental grindcore vets The Locust, Texas-based post-rock band Riftworm and local sludge-metal favorites Sovereign. The show is free, but tips are encouraged to help the touring acts with traveling expenses. The shows start at 9 p.m., with a cassette giveaway during the show. Check out the bands on their respective Bandcamp pages and official sites, and find more at facebook.com/theblockmurfreesboro.
