Guitarist Bill Frisell’s new double LP Orchestras documents two inspired concert-hall engagements arranged by Michael Gibbs for Frisell’s long-standing trio with bassist Thomas Morgan and drummer Rudy Royston: one featuring the nearly 60-piece Brussels Philharmonic, conducted by Alexander Hanson; and one with the 11-piece Umbria Jazz Orchestra, under the musical direction of Manuele Morbidini. But as with so much of Frisell’s music over the past four decades, a relatively straightforward concept and a familiar songbook yield quietly stirring revelations. The music showcases a level of comfort and interactivity that far transcends the vast majority of “with strings” projects on the jazz record shelf. Sweeping orchestration evoking landmark film scores and Gil Evans alike move nimbly within and around the trio’s telepathic rapport, and Frisell’s shimmering trademark tone melds gorgeously with symphonic strings and brass.
