The threesome of Sam Day Harmet on mandolin, Sana Nagano on violin and effects with bassit Zach Swanson teams up with percussionist Billy Martin and violinist Sarah Bernstein for a mix of elliptical bluegrass and avant garde jazz on this session. A quirky “Orange Blossom Bullet Train” will make Vassar Clemons’ head spin, while sounds akin to a Carl Stallings cartoon are evoked on”Metropolitan Special” and Liberty”. It sounds like someone took a bit too much elderberry wine on the wild “Morning Zephyr Waltz” and it’s a wild night at the VFW for the traffic jam of “Liberty”. Was the blue grass smoked?
