Rhyme Asylum, Jam baxter and any british hip hop for that matter.
Mandle, Cheap Sober, Brad Strut and LSD, and any Aussie hip hop for that matter.
Big L, Gang Starr, Jurassic 5, B.I.G, and WTC...If it's American, it's gotta be old school, it's gotta be funky and it's gotta be lyrically amazing. If not, it's trash....imo.
Opeth, The faceless...
Muddy Waters, Eric Clapton
Municipal Waste, Biohazard, Frenzal Rhomb.
Pink Floyd, Cat Stevens, Simon and Garfunkel, Paul Kelly.
Can't think of much else that I really really enjoy.
