Thomas Wilkins conducted a delightfully satisfying concert for the capacity audience arriving after a day’s work. With an easy-going, “Hey, it’s sweet of you to be here” manner, he blended musicology with what’s relevant now. He talked us through the old masters finding their “groove,” highlighting Mozart’s contrasting conversations between sections. With an audience member, Wilkins demonstrated how our movement inspires music as a prelude to three dance related compositions by Haydn, Bartok and Warlock. In a nod to St. Patrick’s Day, Wilkins and the ISO players offered Grainger’s “Molly on the Shore,” in which the Irish reel tune weaves through all the sections in a game of hide ’n’ seek. The 6-7 p.m. concert opened with Mendelssohn and closed with Beethoven. Wilkins returns for the April 24 Happy Hour. See a slideshow of this event at www.nuvo.net/multimedia/.
