Edgar Meyer has seemingly done it all during his career. He has established himself as the world’s leading double bass virtuoso, and he has achieved fame as a Grammy Award-winning recording artist and prestige as a composer. Just about the only thing the 50-year-old Blair School of Music adjunct associate professor has not done is give a solo recital devoted entirely to unaccompanied bass, an oversight he will correct this weekend at Blair. “The program is a little in flux,” wrote Meyer in a recent e-mail, “since this is the first unaccompanied show that I’ve ever done.” A decade ago, Meyer won widespread acclaim for his recording of Bach’s unaccompanied cello suites arranged for double bass. Not surprisingly, Meyer will include Bach’s Suite No. 1 in G major in his first unaccompanied recital, along with one or two of Telemann’s unaccompanied violin sonatas arranged for double bass. Meyer will also perform one or two movements from a new work-in-progress that he is creating for double bass. The rest of the show will feature original material and improvisations. This groundbreaking performance is free.
