Like cheese, classical music is best enjoyed in string form. Snack on the sounds of cultured compositions with today's Groupon: for $19, you get one admission for preferred seating in section B to one show during the Colorado Music Festival, held in the historic Chatauqua Auditorium in Boulder (up to a $42 value). This Groupon may be redeemed starting July 6 for a ticket to any festival concert between July 7 and August 5 (subject to availability). Concerts begin at 7:30 p.m. View the festival calendar here.

In its 35th season, the Colorado Music Festival graces ears with the strums, plucks, and beats of a panoply of talented composers, soloists, and ensembles. The auditorium resounds with world music from eclectic performers, such as Street Drum Corps, which pops with percussive trashcan and barrel riffs, or the jazz-infused improvisation of Time for Three. Celebrate violins and musical yo-yos with a string-studded mini-festival of concertos by Vivaldi, Tchaikovsky, and Sibelius from July 10 through July 17. Festival attendees may indulge their other senses with a pre-concert picnic in Chatauqua Park prior to the performance or during the Talks Under the Tent program on Sundays and Thursdays at 6:30 p.m., which gives fans an opportunity to meet, greet, and play hacky-sack with visiting artists.
