I like to think about stringing songs together like a string of pearls, or a string of beads, but ultimately it has to be stuff that really works with the band, and gives a spin to the older material.
It doesn't take money to have style, it just takes a really good eye. Sometimes you can find amazing culinary antiques that will make it feel like an old French kitchen.
I think we as a band, as individuals, understand that all popular music stems from blues and jazz and even pop, but rock 'n' roll especially comes from blues.
