Going to a Jay-Z concert does not count as supporting local talent. Going to a dive bar in Midtown to watch a guitarist play a couple sets does. Despite being a no frills, grungy, dated dive, SANCTUARY BAR on W. 39th St btw 8/9th Ave has one of the best local talents around. JOHNNY KIRA performs live every Wednesday from 8PMish - Midnight. He covers legendary hits and also performs original music. No cover and drinks are $8 or less.
If you don't live in NYC, find a bar near you and support the local talent!
