Tete Mbambisa has performed and recorded with many of the giants of South African Jazz (Bazil ‘Manenberg’ Coetzee, Johnny Dyani, Dick Khoza, Duku Makasi, Gideon Nxumalo, Dudu Pukwana, etc...), and is one of the very few South African jazz musicians that can claim to have played with the three jazz generations of the last fifty years. His work as a pianist, vocalist, composer and arranger is a landmark on South African jazz history.

After a recording hiatus, Mbambisa returned in 1974 with an octet album, 'Tete's Big Sound' released on a newly formed label, As Shams or The Sun, established by South African record store owner and independent producer Rashid Vally. 'Tet's Big Sound' included tracks like 'Unity' and the 'Black Heroes Lamentation', now considered a classic in the South African jazz underground. The sound that Mbambisa carved in this period was wholly acoustic, and is a style that now is often loosely labelled spiritual jazz, a sound that alludes to deep African textures and rhythms balanced with clear nods to American hard bop and modal jazz, sometimes edging toward free improvisation in echoes of John Coltrane and Pharaoh Sanders.
