Formed by vaunted L.A. composer and multi-instrumental improviser Vinny Golia to perform his ambitiously scaled original compositions, the Large Ensemble has been a powerhouse of the west coast creative music scene for three decades. Now numbering more than 40 virtuoso performers, the orchestra blends Golia’s intricately notated contemporary chamber music with crackerjack improvisation, incorporating extended instrumental techniques, 20th-century idioms and world music concepts. Only a fraction of the orchestra’s huge repertoire is performed live more than once—making each concert a can’t-miss occasion. The Large Ensemble’s latest incarnation is built around the Vinny Golia Electric Sextet: Golia on a dizzying array of winds, plus trumpeter Daniel Rosenboom, saxophonist Gavin Templeton, guitarist Alex Noice, bassist Jon Armstrong and drummer Andrew Lessman. For the first time, the orchestra also features a vocalist, Andrea Young.
