Zombies + Blues + Lindy? Yes, please. For more of this Greek band's first EP, check out The Speakeasies' Swing Band! on CDBaby.
Boilermakers + a jam circle? Yes again. I'm partial to clarinet players in general, it's true, but I do love Paul Cosentino. See the Boilermaker's page to sample more of their music, including one of my favorites: Minor Swing.
