91X

91X (XETRA-FM 91.1) is San Diego's leading alternative rock station and one of the most influential rock radio stations on the West Coast. Broadcasting from the US-Mexico border region since the early 1980s, 91X played a foundational role in breaking alternative rock to American audiences at a time when the genre was still fighting for mainstream space on the FM dial. The station's format covers alternative rock across eras — from the post-punk and new wave artists it championed in its early years to Britpop, indie rock, and the modern alternative releases that define the format today. 91X has a long tradition of supporting local San Diego bands and showcasing live music, making it deeply embedded in the city's rock scene. Its border-crossing nature — broadcasting from the Mexican side — gives it a slightly outlaw energy that suits the genre perfectly. 91X streams live online for free, allowing alternative rock fans well beyond San Diego to tap into one of the West Coast's most respected rock radio stations. If alternative music is your world, 91X has been shaping it for over four decades.
