Rex sings of the American West, from the times of the early explorers, the fur trade, the Civil War and the cattle drive era to the end of the 19th century. From Lewis and Clark to Jack Thorp and Badger Clark he brings to life the music from another time on the instruments from that time. As the proprietor of Time Travel Music, Rex has performed at countless historic sites and museums across the West playing fiddle, banjo, mandolin and other instruments. His music has been featured on television and radio such as CBS Sunday Morning, museums like the Western American Art collection at the Denver Art Museum and the soundtracks of three National Park Service visitor center films. He was involved in the Museum of New Mexico's award-winning book and CD project Jack Thorp's Songs of the Cowboys. Rex also plays fiddle in the blockbuster Dreamworks film, Cowboys & Aliens.
