The co-headliner was Richard Thompson, touring on the strength of his fine new album Electric with a drummer and a bassist. They opened with selections from that disc and peppered it with some catalog choices like "Tear Stained Letter" and a blazing acoustic take on the greatest motorcycle song ever written "1952 Vincent Black Lightning". Thompson was already a guitar virtuoso back in the 60s in his stint with Fairport Convention and he continues to get better. You'd have to call him a rocker, but his style is informed by Celtic reels and fiddle tunes played almost always in a mournful, wailing minor key. At breakneck speed. He joined in with Emmylou and Rodney on "Ain’t Living Long Like This" but let the young hot shot in the headliner combo do most of the work, just like a polite, invited guest would do. Nonetheless, it was certainly one of the best guitar duels ever heard at Orchestra Hall. Everyone went home happy.
