A Tampa Bay band that has its own punk subgenre, “swampcore,” to better incorporate the band members’ diverse musical interests — emo with a grindcore foundation and multiple layers of electric violin. They took their swampcore on the road this year for a 50-date tour, impressive for any band but even more so for DIY locals who really did it all themselves — of course, with a little help from friends along the way. recreantswampcore.bandcamp.com.
