With Whistle Tips, Brooklyn, NY quartet Dinosaur Feathers flee from the tropics of their debut, 2009’s Fantasy Memorial, and push themselves into hitherto unexplored and ultimately rewarding new territories. Once tethered to a drum machine, the addition of drummer Nick Brooks provide new-found forcefulness and flexibility; the clean melodic basslines of Ryan Michael Kelly often grow into dynamic leads without abandoning the low end; and where acoustic guitar once engendered laid-back vibes and folk misnomers,the electric guitar of vocalist Greg Sullow now drives with clear tones, a welcome crunch, and occasionally noisy outbursts. Evolution is, however, only a theory. For all you indie creationists, the Dinosaur Feathers you may have known and/or loved lives on through their sunny melodies, still-infectious grooves, and ever-boisterous harmonies between Sullo, Kelly, and keyboardist Derek “Duck” Zimmerman. These elements, plus such seemingly disparate influences as The Soft Boys, The Olivia Tremor Control, XTC and of course Paul McCartney’s Wings, now inform a jazzier/punkier/maybe even poppier melange.
