Tuesday: Since their legendary 1999 collection "69 Love Songs," the Magnetic Fields have made quick, quirky and clever odes to amore their signature trademark. Songwriter Stephin Merritt (left) delivered some delightfully odd ones on the band's latest, "Love at the Bottom of the Sea," a lighter and poppier collection that landed something of a surprise hit in "Andrew in Drag." Opener Gal Musette is a ukulele-plucking 14-year-old California girl who's penning 70 love songs in response to Magnetic Fields. Oh, fer cute! (8 p.m. Tue. $30. First Avenue, 701 1st Av.
