One of my absolute favorite local acts is progressive-psych trio Moonrises, featuring Plastic Crimewave (aka Steve Krakow) on guitar, Libby Ramer on organ, and Ben Baker Billington on drums. This Monday they’ll be celebrating the release of their new LP, Frozen Altars (Captcha Records), with a free show at the Empty Bottle. Frozen Altars sees the band streamlining what they created on last year’s self-titled full length; it’s got a brighter recording, smoother drumming, and a stronger emphasis on vocal and organ melodies than before. The fresh take on the band’s meandering, proggy compositions results in a fantastic record highlighting each member’s musical abilities, which fall into balance this time around. Ramer’s Keith Emerson worship still lies at the forefront, but Billington is more dynamic than ever and Krakow’s guitar work is expressive and controlled. You can listen to “Lorelei’s Grasp,” one of the record’s many highlights, after the jump.
