Telluride, Colo. (Mtn Press)-It’s the granddaddy of them all! The biggest, bestest summer mountain music festival in the world will return starting tomorrow. That’s right, the 36th Telluride Bluegrass (June 18-21) is upon us!

But it's still not too late to make your trek to Telluride. David Byrne, Emmylou Harris, and Sam Bush will be there; Elvis Costello is bringing an all-star bluegrass band; YMSB and Railroad Earth are ready to kick up some dust; Bela Fleck and Tim O'Brien return with fire and virtuosity. Will you be gazing out onto alpine waterfalls with them? C'mon, it's Jerry Douglas's 25th Telluride - you'd better be.

The 36th Annual Telluride Bluegrass coincides with the Summer Solstice and the days surrounding the full moon; the longest day of the year; the beginning of summer. It's a magical time of sun and light, when the the high country of Colorado puts away its skis and grabs hiking boots, kayaks, and a low-back festival chair to take in "Bluegrass."

Jerry Douglas celebrates his 25th year consecutive year at Telluride Bluegrass. To help him celebrate, he's invited Elvis Costello for a set of bluegrass-inspired music with an all-star acoustic band, The Sugarcanes. Several of Elvis's frequent collaborators, including Emmylou Harris and Jenny Lewis bring their own bands.

One of the defining artists of American popular music, David Byrne, makes his Telluride debut. The musician named the best songwriter of 2008 by Rolling Stone, Conor Oberst, joins us with his Mystic Valley Band.

Yonder Mountain String Band celebrates their 10th year; Railroad Earth returns for the first time since playing one of their first gigs on the Telluride stage in 2001. Punch Brothers featuring Chris Thile follow-up last year's classically-influenced set with an only-in-Telluride traditional bluegrass set titled "Punch Brothers Play & Sing Bluegrass."

The festival is built around the many artists that have defined the Telluride Bluegrass sound. Tim O'Brien & Jerry Douglas open the festival on Thursday morning in a rare duet set; the festival closes with another epic set from the Telluride House Band (Sam Bush, Béla Fleck, Jerry Douglas, Edgar Meyer, Bryan Sutton, Luke Bulla). The weekend is sprinkled with inspired sets from Peter Rowan, John Cowan, Sam Bush, Béla Fleck (with special guest, Malian kora master Toumani Diabate), and many others.
