Chronicle Books has just issued three fantastic new rock-and-roll books, aimed at teen and pre-teen girls who wanna rock, inspired graphic artists, and anyone who's bowed down at the sexy "graphic-ication" of rock-and-roll poster girls. Featuring a foreword by Carrie Brownstein of Sleater-Kinney and contributions by Beth Ditto of Gossip, Hilken Mancini of Fuzzy, and Sarah Dougher of the SG's, Rock 'n' Roll Camp for Girls is an amazing companion to the not-for-profit Portland, Oregon, "summer camp" that began in 2001. Playfully illustrated and smartly empowering, the nearly 200 pages can take a young girl from rock dreams to putting out a CD and going on tour, holding hands through picking an instrument, writing your first song, forming a band, and booking an all-ages show.
