I have been on the road lately, in more ways than one, so have been unable to post regularly. Yet I did learn with sadness of the recent demise of Ndombe Opetum, via the inimitable World Service blog. I highly recommend you go there for a complete biography, pictures and a video.
While I cannot offer any deeper information about "Pepé", I can offer in tribute some music from the masterful composer/singer, who was such a presence in both Afrisa and T.P.O.K. Jazz over many years. Today's record, on the Anytha-Ngapy label, presents two long medleys of Opetum's memorable songs.
Sadly I lost track of the album, so the (pristine) recording here is from the first-play copy I made years ago on a metal cassette. Unfortunately I have no information on the other personnel involved in this tasty session. Perhaps others could enlighten us in the comments?
