Major Zephyr

 Major Zephyr was founded after long-time Jackson Hole musicians Jeff Eidemiller, Pete Muldoon, and Marshall Davis spent a month in Mendoza,  Argentina at La Flora Estudio writing and recording music for a future project. After returning to the US, they decided to name the band Major Zephyr, and their first show was as the opener for Deer Tick. Major Zephyr plays a mix of Americana/Alt Country, and is guitar-driven and thematically political and philosophical. While they play mostly original set for festivals and club dates, they're also comfortable playing a wide mix of genres for weddings and other special events. 

Aside from countless club and festival dates, they've also been billed with national touring acts and Grammy winners such as Steve Earle, Asleep At The Wheel, The Hold Steady, Wendy Colonna, and Deer Tick
