Philadelphia’s Loose Tooth had a fairly inauspicious start. In the summer of 2013, Larissa Sapko had two goals: to find a job and start a band. Once the band got rolling, it quickly built steam, weathering lineup changes and releasing an EP and full-length in fairly short order. Now Loose Tooth is prepping for the release of its second album, Big Day, which will be out in April as a split release between Lame-O Records and Father/Daughter Records. Today, The A.V. Club is streaming ”Garlic Soup,” a song from Big Day that shows a noisy new side of the band. While it’s still poppy, the back half sees the band split away from the song’s established melodies, stepping away from its post-hardcore rocking for something a bit headier, yet still totally heavy.
