This beat has a sampled loop from a vinyl record that is sped up and hard to hear.   I was dealing with pre-done wave chords and other effects, so it was almost a miracle that they came out in key.  I added my favorite piano from Reason - the NNXT piano that loads as soon as you load up NNXT.  The hyphy trumpets and violins give it another crazy feel...but I love anything with piano.
