The Poudre River Irregulars Jazz Band -- As heard on KUVO radio


The Poudre River Irregulars play at a wide variety of events. Public gigs include a variety of scheduled appearances

(concerts sponsored by jazz societies, for instance), and a recurring monthly gig to great crowds at Avogadro's

Number that takes place on the First Friday of every month.

You can book the Poudre River Irregulars. We play for parties, weddings, swing dances, church services and

funeral marches, plus more!  In addition, the "Mini-PRI", a stripped-down version of the band, is available

for groups with tight budgets. To arrange private bookings, use Contact above in the menu.

We hope you'll come and hear us play.

The "Regular Irregulars" are Charlie Smith and Larry Lagerberg on trumpet, Len Kellogg on trombone,

Clark Burnside on clarinet, Ray Leake on piano, Alan Sparks on bass, Rory Thomas on banjo,

and Oscar DeZoto on drums.
