Among George Gershwin's most celebrated compositions, the jazz-inflected “Rhapsody in Blue” is perhaps his most groundbreaking, with a freewheeling syncopated piano leading a full orchestra. Since its debut in 1924, “Rhapsody” has become one of the most frequently performed works of classical music, and its influence is felt on everything from ragtime to film scores. While everyone recognizes the tune from just a few notes, only music lovers and history buffs know that it was originally commissioned by bandleader and Denver native Paul Whiteman. Hear the wonder for yourself when conductor Brett Mitchell and pianist Kevin Cole lead the Colorado Symphony through Gershwin's masterwork, as well as Missy Mazzoli's “These Worlds in Us” and Pytor Ilyich Tchaikovsky's Symphony No. 5 in E Minor, Op. 64, at Boettcher Concert Hall, in the Denver Performing Arts Complex. Ticket prices range from $20 to $99; performances are on Friday, September 22, Saturday, September 23, and Sunday, September 24. Find tickets and information at tickets.coloradosymphony.org.
