Machetres first stumbled onto the local scene on Sept. 3, 1997, opening the 10th-anniversary celebration of Fugazi’s first show at Wilson Center, a benefit for the Latin American Youth Center. The trio were high school seniors at the time, hesitant young musicians trembling in disbelief at their sudden good fortune. Now, just over a year later, their stage jitters seem to have dissipated, and they’ve got a quirky new record out, a three-song 7-inch produced by Guy Picciotto. The best track on the record is “Aerolinea,” a fast-paced song with lyrics in Spanish and a quick ska beat that bears Hispanic folk music influences and mean guitar riffs. (CB)
