Like you, I first heard Kippie Moketsi through Ibrahim -- and Basil "Mannenberg" Coetzee too.
I'm no expert on Cape Jazz, but I like Tshona very much. You can give it a listen here: https://as-shams-busy-bodies.bandcamp.com/album/tshona
Next up:
Art Pepper - Tokyo Debut (Galaxy, rec. 1977)
On this tour, Pepper was backed by Cal Tjader's band -- with Clare Fischer, Poncho Sanchez, a.o. Tjader also sits on three cuts.
