My Morning Jacket is one of the best live acts on the rock circuit today, period. The Louisville, Ky., band has effortlessly evolved from twangy alternative country to psychedelic to fundamental pop in its 13-year career, and with 2011’s “Circuital,” the quintet is (appropriately) back to where it started: with Jim James yearning his heart out atop howling guitars. Catch the band at Red Rocks Amphitheatreon Thursday night with neo-soul star Amos Lee as support. Tickets, $43.50, are available through Ticketmaster.
Bluegrass, mountains, a picturesque creek and . . . Steve Martin? The 39th annual RockyGrass Festival will take over the Planet Bluegrass ranch in Lyons this weekend. Think Telluride — but smaller, cozier, and only one hour from Denver instead of eight. Headliners include the Del McCoury Band, Steve Martin & the Steep Canyon Rangers, Hot Rize and Sam Bush Bluegrass Band. Tickets are sold-out, but try your luck on .
