Brooklyn electro-pop duo Holy Ghost! returns to the fold with the release of their second studio album, Dynamics. Nick Millhiser and Alex Frankel of Holy Ghost! use a variety of instruments — violin, drums, bass, percussion, synthesizers — to create an upbeat and feel-good album that has the ability to bring out the groovy side in all of us. Lead single “Dumb Disco Ideas” combines synth with drums and bass for an eight-minute funk fest. Some tracks start strong, like the hook-laden “Okay,” while others, like “I Wanna Be Your Hand,” start slow and worm their way to a catchy disco-inspired beat. And there are guest stars, too, including Neon Indian’s Alan Palomo and former LCD Soundsystem singer/keyboardist Nancy Whang. As a whole, Dynamics lives up to its title thanks to a catchy blend of vintage sounds with modern effects, making for an album that’s both a step forward and a must-listen. Holy Ghost! plays at Velvet Jones on Friday, October 18, as part of the New Noise Music Festival. Visit newnoisesb.org for info.
