Unfinished Business
Meeting as students at the California Institute of the Arts, the four members of Slumgum (the name is a beekeeping term) brought varied musical backgrounds to the quartet, and the CalArts program encouraged them to explore other musical traditions and incorporate them into their jazz studies. That, in part, explains the various influences they bring to bear on their compositions. Shadowed by Brahms, Cowal may be laying down a bed of shimmering romantic arpeggios on the piano while Armstrong soars over it, his free honks spiced with Carnatic elements. Tranchina and Anderies, meanwhile, might be working out a rock and roll rhythm underneath.As varied as Slumgum compositions are, ranging from hard-driving postbop epics to short impressionistic poems, most share another quirky characteristic: unexpected but nonetheless well-integrated shifts in texture, rhythm, genre or mood. An unusual compositional technique accounts for those shifts.Armstrong notes that an album featuring compositions from four different contributors, four different sensibilities, could be disorienting for listeners. Beginning with its second album, Quardboard Flavored Fiber, the quartet found a way to incorporate each voice while creating a unified, identifiable sound: They starting bringing unfinished compositions to their sessions.“We sort of stumbled on it, but now we recognize it as a strength,” says Armstrong. This allows each member to play around with the composition and make suggestions, adding a needed melody, say, or a bass line. This approach requires a longer gestational period to achieve a complete composition, says Armstrong, but the result is a more coherent album—with those unexpected shifts reflecting the influence of the different voices.Dangerous Duos
For their appearance at The Roost, Slumgum has chosen to open the first set and close the second set as a quartet, but in between, they will perform 12 duet pieces. Each member is writing three new compositions, one for each of the duets that can be formed by the other three.“Part of our sound has been generated by duo practice,” says Armstrong. It’s a technique the group uses to work out challenging sections in compositions and keep the gestational process moving forward.The quartet wants to showcase that process, but there’s danger lurking. “It’s like a game,” says Armstrong. “You can pull pranks. Since you’re not playing, you can write some real hard stuff and say, ‘Aww, learn it!’ ”Game on.SlumgumSunday, Sept. 9, 7:30 p.m. The Roost—Outpost Performance Space 210 Yale SETickets: $5, all-agestheroostabq.comslumgum.com
