There are at least three acts / bands called Gumm (or GUMM, or GuMM). 1. Gumm is a melodic hardcore band from Chattanooga, TN, United States. With a penchant for emotive melodies and high-energy musical arrangements, Gumm creates tunes that put them in the same sonic wheelhouse as bands like Praise and Turning Point. 2. Gumm was a British bubblegum rock act from the early 1970s. Hopelessly anonymous, we know that their two singles were overseen by Belfast-based producer Arthur McClintock.
