If the names are unfamiliar, you probably know their old band, the Bourbon Tabernacle Choir. Both Brown and Fenner are excellent artists, as are the other four musicians they've enlisted into the ranks for this EP, but the political-pandering protest-poem-as-song theme quickly wears thin and grates deep. Part of the problem is Fenner's Tracey Thorn-meets-Dido delivery, which keeps the songs from attaining the desired anti-war edge. Whatever it is, Go On comes off as preachy as Sunday-morning TV with a musical backdrop most elevators would reject. Brown & Fenner hit the Horseshoe tonight (Thursday, October 21).
