The title of Albino Fly's demo, Easy as One, Two, Three, capsulizes the group's musical strategy, which includes generous samples of each facet of heavy music's current reigning trinity: sludgy postgrunge, low-end-scraping Korn metal and a vocal attack that incorporates rapping and tuneful singing into the string of shouts. It also summarizes the telling trio of covers the group tends to include in its ninety-minute sets: Faith No More's "Epic," Pantera's "Mouth for War" and Tool's "Cold and Ugly." And three is the number of intriguingly named members in this five-piece band, which includes guitarist Poe (not that Poe), drummer Dust and vocalist Vanity Mason.(Guitarist Nathan Alexander and vocalist Jon Collichio sport low-key monikers.) But most likely, the disc's title refers to the fact that it contains three tunes: a gurgling low-end number with an emotive chorus; a densely layered song that features a quick-paced vocal delivery; and the closer, which starts heavy, mellows out for an interval, then finishes loud after a shouted "Fuck" reopens the floodgates. Albino Fly hopes to play to more than three people when it takes the stage for a free open mic at The Bottleneck Monday night. Earlier in the evening, a group of Lawrence sixth graders (Mr. Machine) joins some grown-ass men still operating with the mentality of sixth graders (The Queers) plus three pop-punk bands that aren't above a little immaturity (Teen Idols, Pinhead Circus and resurgent locals Bubble Boys).
