Don Letts provides an important lesson in the fact that even if you don’t play an instrument, you can still be a part of the music industry, and not just on the business side either. He got his start as a DJ, and is widely credited for introducing reggae into the burgeoning punk rock scene in London in the 1970s, but he doesn’t want all of that credit.

You know Butch Vig as the drummer and producer of Garbage, or you know him as the producer of genre-defining albums from Nirvana and Smashing Pumpkins, but there is more to him than that. He has been working with most of the people he makes music with for more than 30 years. The new Garbage album, No Gods No Masters, is out now.
