Third Coast Percussion’s 20th anniversary album celebrates ensemble’s legacy of musical collaboration and artistic growth since its founding in 2005. The program of world premiere recordings explores the passage of time, both through the eyes of percussionists charged with “keeping time” for an ensemble, and on the grander scale of time elapsed over decades. The album opens with Jlin’s Please Be Still, a piece inspired by the “Kyrie Eleison” movement of J.S. Bach’s Mass in B Minor. Tigran Hamasyan’s Sonata for Percussion is a three-movement work that bends and stretches time through the composer’s fantastically complicated rhythmic language. Zakir Hussain’s Murmurs in Time represents the late tabla master’s only composition for a classical percussion group. Jessie Montgomery’s Study No. 1 was originally composed for the Percussive Arts Society’s International Convention, where TCP’s real-time creative contributions made them a “musical laboratory” for the composer, yielding the first in their ongoing series of collaborative works. A second Montgomery work on the recording, her three-movement In Color Suite, emerged during workshops with TCP for her Study No. 1, where she used excerpts from various pre-existing works to experiment with percussion instruments, exploring timbral possibilities, and the blending of sonic colors.
