for the pow pow, i like to go with funk and old motown. #1 is MJ's Thriller album. its like making love to the snow. its almost unfair once ya get some marvin gaye, al green, aretha franklin, stevie wonder, and the temptations gets goin. that shit'll make mountains pregnant.
for park/jumps i'll mix some dirty swamp blues and metal in with the motown. The Black Keys, JJ Grey & Mofro, Buddy Guy, Tony Joe White, the Allmans. then some heavy shit with Pantera, Lamb of God, A Life Once Lost, Killswitch Engage, Anthrax, Slayer, etc.
