There is a little band in Willoughby, Ohio, called the Amazing Rondini Brothers. One of the players described it as "forties-era music with some klezmer thrown in, but punk." At the concert I went to, they had six guys playing; violin, trombone, trumpet, electric guitar, bass, keyboard, and drums. I was quite impressed. They are a bit similar to the Squirrel Nut Zippers, but I much prefer the Amazing Rondini Brothers. Check them out.
