Jeff Cox, resident DJ at Cecilia's Nightclub in Breckenridge, Colorado, has been a prominent figure in the digital music and party scene in the mountains of Colorado for the last 10 years. With him at the helm, Cecilia's has reached legendary status as the ultimate mountain party bar. Peaks Magazine named it the best party bar and best dance bar in their article Nightlife Supremacy; Breckenridge and Vail Face Off by stating "the most sought after boys and girls seem to be under its’ spell." It was notably the only club to win two categories.

Cox has an undeniable energy and a unique talent to flow through tempos and genres in such a way that lures even the most timid listeners into the party.
