I suppose if Jack Kerouac had never written On the Road, The Doors would never have existed. It opened the floodgates and we read everything we could get our hands on -- Howl, Allen Ginsberg; Gasoline, Gregory Corso; A Coney Island of the Mind, Lawrence Ferlinghetti; Peyote Poem, Michael McClure...
All mind-benders, soul-twisters, heart-openers, foot-tappers, bone-crushers, eye-wideners... and general fine things. I suggest you read them all.
