The Guide goes from the macro (the philosophy of Creative Commons, the value of audiences beyond immediate music sales) to the micro (how to manage your rehearsal space), and covers an immense amount of technical minutae (how to use compulsory mechanical licenses to record and distribute covers; which places to sell your music to ensure maximum PRO payouts; how to mix down and master a CD).
But where it really shines is in the creative strategies for attaining popular and commercial success, drawn from the direct experience of indie musicians who've found joy by, for example, cold-calling websites that cover subjects related to their music (crocheting, beer-drinking, and everything in between) and suggesting featuring their music, or offering extra CDs from the duplication plant in plastic sleeves with liners advertising upcoming gigs to be sold for $1 by local music retailers (with the retailers keeping the whole sum), a strategy that got Beatnik Turtle free point-of-sale promotion at all their local record stores.
Chertow and Feehan began the guide as a free, Creative Commons-licensed download and were picked up for print publication by Macmillan in the USA, and various major publishers all over the world. They're tireless, principled, talented, funny, and passionate, and this is just the sort of zero-BS guide to modern artistic survival that should be in every artist's handbag.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
