5th Anniversary: Marijuana Law For Musicians By Jamie Spencer on April 19, 2010 Posted in Marijuana & Controlled Substances Tonight! 8 p.m. Free. At the Mohawk: If you haven’t caught it the first four times, you’ll definitely want to go see Charlie Roadman’s Marijuana Law for Musicians. My excuse for the late posting is not that I’m forgetful. Not at all. I figured you wouldn’t remember if it were mentioned too soon, therefore, a last minute reminder. Review of the 2007 edition here, and it just keeps getting better every year.
