Once again, your favorite brass musicians are headed for the grand steps of the Old Capitol Museum for Iowa City's beloved annual tradition (since the 1970s): Holiday Tubas!

The University of Iowa School of Music and the Pentacrest Museums invite guests to enjoy classic holiday tunes while getting in the giving spirit on the Pentacrest. Here's everything you need to know:

TOY DONATION: As is tradition, the crew will be collecting new, unwrapped toys for Holiday Shop of the Iowa City Domestic Violence Intervention Program. Bring a toy to donate!

TREATS: Directly following the performance, the Old Capitol Museum welcomes all inside to warm up with cookies in the beautiful, historic space at the heart of our great city.

LET'S GET FESTIVE: The performers are hoping to encourage all participants and attendees to don their most festive apparel to help make this years performance the most visually colorful and festive yet. Break out the ugly X-mas sweaters, folks!

PERFORMERS: The musicians are made up of University of Iowa Associate Professor of Tuba and Euphonium John Manning's studio students, joined by several alumni, adult enthusiasts and other students. **OPEN CALL** - anyone with a tuba, sousaphone or euphonium is welcome to join in playing. Bring your instrument, arrive at noon inside Old Capitol Museum, and plan to play from 12:30-1 p.m. outside on the steps for a cheerful crowd.
