There are plenty of great musicians in town, but precious few earn the title living legend, as blues maestro Tomcat Courtney has. Now 82, Courtney has mentored dozens of San Diego’s performers and still keeps a live-music schedule that would wear out most younger performers. A staple of local street fairs and bars, his main haunt these days is The Turquoise (Café-Bar Europa), where he can be found playing dinner time sets Wednesdays, Fridays and Saturdays. If you’re a fan of the blues or simply want to pay your respects to one of the foundations of San Diego’s music community, be sure to catch one of Courtney’s sets — you won’t be disappointed.
