A hardcore metal Seinfeld band called Grindfeld exists

There's a Seinfeld-themed hardcore metal band from New York City (of course) called Grindfeld.
Born out of a mutual love of Death Metal, comical observations, coffee and Hardcore, Grindfeld is a project built on the existential dread hidden just under the surface of daily life.
Yes, they're real and they've got '5 Songs About Nothing.' The first is a loud little ditty called 'The Contest':

The other four songs -- The Soup Nazi, The Limousine, The Bizarro Jerry, and The Letter -- are available from their $5 digital album. They also have merch.
