Those who lament the homogeneity and predictable playlists of traditional radio stations now often just switch to satellite providers to get their radio fix. But St. Louis is lucky to have our own version of satellite radio on the terrestrial airwaves, courtesy of the station run by students at Lindenwood University in St. Charles. Nicknamed "The Wood," 89.1 FM's only rule is that there are no rules. Non-singles, B-sides and even acoustic takes earn generous spinsdiversity that underscores the station's expansive playlist, which shies away from excessively repeating tunes. The Wood's bread-and-butter is the coffeehouse singer-songwriters and granola rockers popular with college kidsColdplay, Death Cab for Cutie, Jack Johnson, John Mayer, etc. But diverse genresnew wave (Men Without Hats, Depeche Mode), classic rock (Steely Dan, Elton John), emo (Fall Out Boy, Hawthorne Heights)are well represented. Any doubts about the station's commitment to unorthodoxy are put to rest by the weekly Sunday lineup: a three-hour acoustic show in the afternoon, and a four-hour block of classic hard rock at night.
