Thou shall not mix rock and rap.
Thou shall sample it. This any dedicated rap listener have been knowing.
A guitar solo gets the Fast Forward-button instantly.
But sample a guitar, loop it, filter it, and you have yourself some Boom Bap. From Kurtis Mantronik sampling Thin Lizzy to that incredibly harsh beat El-P made for that lost The Weathermen posse cut that was on mp3.com or some such ancient site that probably only I remember and which I’d probably be very disappointed by if I heard it now to the incredible treatment of acoustic guitars by RZA, Muggs, Fugees, and so on.
