When Dave Mason joined up with Steve Winwood at age 18, he surely couldn’t have known that he was going to make music history. Of course, any discerning music fan will tell you that that’s just what Traffic did. The band kicked off a long and fruitful career for Mason, who has appeared on records by The Rolling Stones, George Harrison, and Jimi Hendrix, among others. On his own, Mason is every bit as relevatory; his guitar playing is something you have to see in person in order to get the full experience. Luckily, he’s giving New York fans a double dose of blues rock with a two-night stand at City Winery. For more information and to purchase tickets, visit the City Winery website.
