Jason and the Scorchers are aptly named. After 30 years on the road, the Nashville, Tenn.-based country rock band continues to blow away audiences with their antics on acoustic guitars ablaze with boundless energy and seasoned with the twang of a honky-tonk harmonica. They arrive at the Iota Club on Friday semi-direct from Rams Head Tavern via Pittsburgh and suburban Philadelphia.

The subject is “Halcyon Times,” their first album with all new material since 1996, an accomplishment befitting the Lifetime Achievement Award winners at the 2008 Americana Music Conference. The opening number, “Moonshine Guy,” is glorious fun and leads the listener right into fresh new songs that go back to their roots with vigor, the obligatory country pathos and the dynamic power ably expressed in “Shot Down Again” to leave everyone bathed in sheer joy.
