by Heather PharesAs passionate as ever, but now with a little more polish, TV on the Radio's second album (and Interscope debut), Return to Cookie Mountain, is their most satisfying work since they exploded onto the scene with Young Liars. More than some of their indie rock peers, TV on the Radio seems comfortable on a major label. They've always been a band with a big, unapologetically ambitious sound, and on Return to Cookie Mountain, they give that sound room to breathe with a lush, expansive production. The sonic depth throughout the album is a sharp contrast with the density of their first full-length, Desperate Youth, Blood Thirsty Babes, which was so jam-packed with sounds and ideas that it was nearly suffocated by them. However, Return to Cookie Mountain is hardly slick or dumbed-down for mass consumption. In fact, the opening track, "I Was a Lover," is one of the band's most challenging songs yet, mixing a stuttering hip-hop beat with guitars of Loveless proportions and juxtaposing inviting vocal harmonies and horns with glitches and trippy sitars. "Playhouses" is only slightly less radical, with its wildly syncopated drumming and Tunde Adepimbe's layered, impassioned singing. At times, Return to Cookie Mountain threatens to become more impressive than likeable -- a complaint that could also arguably be leveled against Desperate Youth as well -- but fortunately, TV on the Radio reconnects with, and builds on, the intimacy and purity that made Young Liars so striking. David Bowie's backing vocals on "Province" are only one part of the song's enveloping warmth, rather than its focal point, while the album's centerpiece, "A Method," is another beautiful example of the band's haunting update on doo wop. Meanwhile, the mention of "the needle/the dirty spoon" on "Tonight" cements it as a gorgeous but unsettling urban elegy. As with all their other work, on Return to Cookie Mountain TV on the Radio deals with the fallout of living in a post-9/11 world; politics and morality are still touchstones for the band, particularly on the anguished "Blues from Down Here" and "Hours," on which Adepimbe urges, "Now listen to the truth." Notably, though, the album builds on the hopeful, or at least living for the moment, vibe that emerged at the end of Desperate Youth, Blood Thirsty Babes. The sexy, funky "Wolf Like Me," which is the closest the album gets to rock in any conventional sense of the term, and "Dirtywhirl," which spins together images of girls and hurricanes, offer erotic escapes. And by the time the epic final track, "Wash the Day," revisits the sitars that opened the album with a serene, hypnotic groove, Return to Cookie Mountain gives the most complete representation of the hopes, joys, and fears within TV on the Radio's music.
