Guilty Simpson

The Motor City emcee Guilty Simpson released a soulful Katalyst produced track “Testify”. The Detroit natives are frequent collaborators sharing a little heat while Guilty is working on his latest studio album. This album will be the follow up to the September release of his Detroit’s Son LP in 2015. This latest single will hold the fort down until the official album release. In the meantime and in between time Guilty Simpson will be on tour in the land down under Australia for the next few weeks
