Michael W. Dean’s $30 Music School.
Five hundred + pages of everything the DIY creative person needs to know, from starting a band to writing your own contracts… it’s chock-a-block (and how often does one get to use that old saw???) with tips and useful anecdotes that only someone who’s a peer with Ian MacKaye and Henry Rollins could know.
Seriously… some of the stuff you’ll know, some of the stuff you forgot, and some of the stuff you didn’t know you needed to know. It’s all in here.
I don’t plug often… listen!
