DJ Quik is THE quintessential (sp?) musician in rap music, definitely. His arrangements ever since his 3rd record leading up to Trauma have been deeper than the average hip-hop head can digest. Rap isn't supposed to have cow bell, chimes, lead guitar, real piano, blah blah blah. It's sad that Quik tried to ride ahead of everyone else, and not many people caught up to him, that's why his sales suffered. The music was still, is still great, though.
In a perfect world, if real musicianship was rewarded and celebrated in ALL forms of music, Rhythm-al-ism would have been 8x plat., Balance & Options would at least have been double platinum, 2nd-II-None's second record would have won a grammy, and Robert "Fonksta" Bacon would guest guitar on every Rap & R&B record from coast to coast. Rick James would be remembered for Street Songs and not for "I'm Rick James, bitch!"
