Heartless Heathen is the third album by Detroit garage rock/punk trio Timmy’s Organism and their first for Third Man Records. Once again, Timmy’s Organism finds it sound through a mix of 70s rock and protopunk, garage rock, grimy punk, experimentation, blues, and noise. The melted sounds of rock ‘n’ roll show them as kindred spirits of the trip metal gods Wolf Eyes, a band they are currently on tour with (stopping tonight in Boston with a slightly altered lineup of Timmy’s Organism/Video/Regression 696). Tracks like “Please Don’t Be Going” appear firmly in the tradition of 70s rock, at a point where anything goes as long the song is rocking, but this sensibility is belies an affinity for, among other things, the contemporary lo-fi punk and garage aesthetics of labels like HoZac and Sacred Bones, where elements of post-punk and quasi-psychedelic rock burrow their way deep into the angular, feedback-heavy crunch of the music. “My Angel Above,” on the other hand, sounds like The Afghan Whigs by way of Iggy Pop. Heartless Heathen is filthy, warped, and all-around freewheeling fun. Let your minds drip out your ears as waves of the second coming Detroit ’75 wash over you.
