Mark O’Connor’s Appalachian Waltz Trio: Crossing Bridges

Violinist and composer O’Connor made two fine classical-Americana albums with cellist Yo-Yo Ma and bassist Edgar Meyer, but the trio’s concert performances were limited because, let’s face it, Mr. Ma has a few other gigs going. O’Connor does, too, but he’s assembled a new trio with Natalie Haas on cello and Carol Cook on viola that reworks these tunes in a recorded concert performance. Rather than fading into the background of a PBS documentary, this rustically elegiac music rushes to the fore and commands your full attention.
