Depends on where I am geographically, and the time frame. If I'm crusin' thru the mountains Bo Hansson's Magician's Hat or LOtR, Terje Rypdal, Eberhard Weber, or John Abercrombie. If I'm beatin' feet thru the flatlands The Doors, Rory Gallagher, Spririt, Little Feat, maybe even a little REO Speedwagon.
