On December 12, the Portsmouth Symphony Orchestra will perform the second of six chamber music concerts this season at Jimmy’s Jazz & Blues Club, located in a restored 1905 former YMCA building in Portsmouth, New Hampshire. The concert is part of a new “Up Close and Personal with the PSO at Jimmy’s Chamber Music Series” exploring jazz and classical music. Concert tickets include food and drink. The December program will feature the PSO Brass Quintet tracing a history of brass music from post-Civil War New Orleans to modern and post-modernist styles. Additional concerts in the series include “Rhapsody” (Jan. 2022), “Respiro di colori” (Feb.), “Strings + One” (April), and “Intimate Voices” (May). The Portsmouth Symphony Orchestra’s 65 musicians include local professionals, educators, amateurs, and advanced students, all of whom are required to be fully vaccinated. Jimmy’s Jazz & Blues Club requires proof of vaccination or a negative test within 72 hours in order to attend events; masks are highly encouraged until patrons are seated.
