Tetsuo is one of the best rock ‘n’ roll outfits to emerge from Murfreesboro in the past few years, but it’s hard to catch them out in Nashville proper in terms of venues. So make sure and catch them shredding at The Springwater this Saturday with Seafood Hotline, and give a listen to their shabby punkish record, These Crystals Don’t Burn. 9 p.m., $5.
