Thereâs no unifying album concept or gimmick involved in the Magnetic Fieldsâ newly released Love at the Bottom of the Sea, just a return to the catchy, synthesized electropop tracks that made 69 Love Songs a towering success. Clever songs like âGod Wants Us to Waitâ and âAndrew in Dragâ (A pity she does not exist/A shame heâs not a fag/The only girl I ever loved was Andrew in drag) will make you spontaneously shit envy for songwriter Stephin Merrittâs wit, and watching Merrittâs clubfooted banter with bandmates and adoring fans (he hates performing live; âI donât see the point,â he told me recently) is a pleasantly engrossing performance in and of itself.
