BRUNSWICK — For two years, composer and upright bassist Joshua DeScherer has been organizing and curating a new music series at the performance space at Frontier Cafe, Cinema & Gallery.

The next installment, on Thursday, Sept. 27, at 7 p.m., will feature the work of Maine-based improvising musicians.

This is the fifth concert this year in DeScherer’s “Frontiers of Music” series, which, according to a news release, has quietly and steadily been featuring some of the biggest names on the Maine contemporary music scene. Composers and improvisers who have been featured on the series include Beth Wieman, Phil Carlsen, Mark Tipton and Richard Nelson.

A news release describes the event as follows:

Frontiers of Music No. 5 will feature five improvised performances. Christopher Cathode weaves percussion, electronics and amplified “found-objects” — often abandoned medical and industrial devices — into a post-apocalyptic sonic landscape that brings to mind a landscape of abandoned factories and dwellings.

Contrabass soloist Joshua DeScherer presents a virtuosic solo performance featuring extended techniques, and drawing upon the stylistic variety in Dr. DeScherer’s musical background.

Trumpeter Mark Tipton and shakuhachi player Phil James will play as a duo, blending the sounds of two culturally and sonically disparate wind instruments.

Ben Gallagher (percussion), Nick Dentico (bass guitar), and Sequoia Leaf will play as a trio; and the lineup is rounded out by the Richard Nelson Imaginary Ensemble, a flexible and genre-bending ensemble that is able to explore a tremendous variety of music within a single performance

Composers and performers are on hand after the performance to answer questions or just generally greet listeners.

The final concert in the 2012 concert series is scheduled for Nov. 29.

Admission to the concert is pay-what-youwant.
