Commercial radio gets lamer with each passing year, which only makes Radio 1190 sound stronger by comparison. Because the station is staffed by students from the University of Colorado at Boulder, the turnover is continuous. Yet the outlet has maintained a high level of quality, thanks to the most eclectic playlist in town (one recent hour ranged from Mi and L'au to Herb Alpert and the Tijuana Brass) and great specialty shows such as Under the Mattress, a Sunday show focusing on vintage rock. This is a commercial-free oasis in a desert of radio mediocrity.
