Another highlight of The Brewing Network’s Winter Brews Festival, held yesterday at Linden Street Brewery in Oakland, was the music. There were some terrific bands playing. But my favorite was, as usual, the down home blues stylings of Tony Magee, owner of Lagunitas Brewing. He taught himself to play just a few years ago and in fact his debut performance was at the Celebrator 15th Anniversary Party when we held it at the Great American Music Hall in 2003. Since then, Tony’s been getter better every time I see him play. Here he is performing a Big Bill Broonzy song, Key to the Highway.
