Davey Gravy has 10 Marcy Playground concerts.

Marcy Playground is an American alternative rock and post-grunge band. Named for the formative location in lead singer John Wozniak's childhood (the Marcy Open grade school in Minneapolis, Minnesota), Marcy Playground emerged in the late 90s. They had been influenced heavily by Kurt Cobain and his band Nirvana. The influence is quite clear on Marcy Playground's self-titled album, with songs like The Shadow of Seattle and Saint Joe On The School Bus.
