From the Velvets to the Voidoids
Although the book was originally published way back in 1993, From the Velvets to the Voidoids, apparently the book to get if you want to learn all about the American punk scene, has been edited and updated for 2005. And it has a way cooler cover, too!
The book looks really interesting, and seems to have been exhaustively researched by the author, Clinton Heylin. I really think I should buy it at Amazon.com, and everyone else should too!
The book is a massive 426 pages and is based primarily off of first hand accounts and references, so it should be a rather accurate representation of the early American punk scene!
The author, Clinton Heylin, has written some other interesting books, including All Yesterdays' Parties (a book about the Velvet Underground) and Bootleg!, a book concerning the "rise and fall of of the secret recording industry." I want to read his stuff!
