I played two concerts with Idrees Sulieman in June of 1990 - Mannes College and Temple University - in a group with Ralph Moore, Peter and Kenny Washington, playing Idrees' tunes. He was a very nice, soft spoken guy and played with a big fat sound. One of the ORIGINAL bebop trumpet players, he had his own thing alongside Dizzy and Fat Girl. Probably one of the most lyrical trumpet players of all time.
I met him for the first time at Sadik Hakim's apartment around 1980. He had a tape of Oscar Dennard playing solo piano at a house party: Boplicity and Round Midnight. Unbelievable. Beautiful smooth block chords. I regret not getting a copy of that. I think Jamil Nasser has it.
I don't think there are any commercial recordings that really show what Oscar Dennard could do.
I'm glad to see Idrees' name mentioned here.
