Autumnal melodies; folk-based, stripped-down arrangements; and dusky vocals are making a comeback. Remember The Band's "Music From Big Pink" and Nick Drake's "Pink Moon." Two of the year's most talked-about albums: The self-titled debut by Seattle quintet Fleet Foxes, and "For Emma, Forever Ago" by Bon Iver, fronted by singer-songwriter Justin Vernon. More hot bands, from Tribune rock critic Greg Kot No Age: Los Angeles duo blends agit-prop political views with bash-and-crash power. Vivian Girls: Named after the heroines in outsider artist Henry Darger's epic novel, this Brooklyn trio delivers buzzing pop songs about onrushing adulthood. Kid Sister: Chicago rapper Melisa Young's awaited debut album is done and should be out soon. She's gotten a massive buzz thanks to her Kanye West-assisted Internet hit "Pro Nails." Led Zeppelin: Even without Robert Plant and the late drummer John Bonham, the Zeppelin brand name will ensure that the reunion of Jimmy Page and John Paul Jones on tour next year will be a commercial windfall.
