Rap was facilitated by digital recording, which enables sampling and thus the construction of a universal palette of sounds even in a bedroom Portastudio of one's own.
Recorded by Clash roadie Baker Glare, who was learning the intricacies of a Portastudio and mixing on the job, the quality varies from patchy downwards.
During the past 17 years, my personal studio has morphed many times - from a Portastudio to an 8-track to 2-inch 16-track, and finally to 24-track.
