Tenko - you joking?! Paul Simon of Simon & Garfunkel fame. He released a groundbreaking album in 1986 called "Graceland".
Usually I like fairly esoteric and obscure music, but I'm happy to admit this album still sounds great. What was so unusual is that he included loads of South African influences, but whereas that would render the work of most artists unlistenable or pretentious, it resulted in his best solo album.
