***BOBSLEIGH BABY began in the east Rome scene as a drum/guitar duo playing what they called “superfluous and idiotic rock’n’roll,” which is to say stripped-down, to the point, excellent tunes: ‘60s garage and girl group filtered through punk minimalism. They have since grown to a four piece of French and Italian folks, adding organ and bass, as well as a more pronounced urgency to the songs on their new Improved LP. The drums have become more forceful while remaining economical. The ever-fuzzed, velcro bass pushes the songs, filling out the low end sonics. The guitar plays like a spaghetti western, thin and reverberated and melodic, while male and female vocals push a sing-song taunt through the organ’s mysterian buzz. This one is catchy.
