Dave Grohl, an ex(?) punk rocker from the band Nirvana and now of his own band Foo Fighters, set out on a project of discovery and found the interconnectedness of many popular forms of music from blues and jazz to country and rock. He was tremendously affected by New Orleans where he connected with the Preservation Hall Jazz Band and partook in a traditional Sunday jazz march through town. To me, it is interesting that a Punk Rocker discovers Jazz.
