Today, we'll meet a few and hear what may be the most talented crop of buskers in the world.

They call it a tent, but it's really much more than that. It has a solid roof, and can seat nearly 2,000 people. But it's the movable side panels that make the Benedict Music Tent such a favorite of Aspen concertgoers. When the weather is nice, those panels open up and allow the gorgeous sounds to waft out over the lawn. You can bring a picnic, bring the kids, even the family dog. Today, we'll meet some folks on the lawn outside the Benedict Tent, and hear highlights from the great concerts inside.

Every week on our Piano Puzzler, composer Bruce Adolphe re-writes a familiar tune in the style of a classical composer.

Teacher and pupil both had wicked senses of humor. But the teacher always maintained a certain emotional distance in his music, more comedy and less pathos. It was the student who ventured into darker emotional corners. In today's show, a work by the student, Wolfgang Amadeus Mozart. His String Quartet No. 15 is almost unrelentingly dark. Mozart dedicated the work to his teacher, the sunny, funny Joseph Haydn.

Scientists tell us life on earth evolved from a murky, primordial stew. Oxygen and hydrogen from the early atmosphere, iron and calcium from the bellies of exploding stars, a dusting of carbon from wayward meteors. At the dawn of the 20th century, Richard Strauss wrote an extravagant piece of music depicting the evolution of humanity, beginning in that murky darkness. We know "Also Sprach Zarathustra" for its 90-second opening. Today, we'll hear the entire half-hour-long tone poem, from a concert in London.
