If you like erudite and sharp-witted cultural criticism you'll want to get your hands on this forthcoming collection of essays by Alexander Theroux, titled The Grammar of Rock: Art and Artlessness in 20th Century Pop Lyrics, when it's released in January. Covering a century of pop music from Ira Gershwin to Ghostface Killah, Theroux deconstructs and evaluates the very nature of the pop song. We're just putting on the finishing touches and packing it off to the printer and, by gum, it's 160 pages longer than when we first announced it. And why yes, that is a vintage Robert Crumb drawing on the front cover.
