Roditi was a superb trumpeter and seriously underappreciated IMHO. Saw him twice in the 1990s: at the Wigan Jazz Festival with his frequent partner Paquito D'Rivera in a phenomenally hot quintet with a Latin rhythm section (I came out saying it was like listening to the Adderleys, whom I'd heard 25 years earlier), and in the Gillespie United Nations Orchestra (lot of joshing with Diz who kept mispronouncing his name as Rodichi). Very sad to see him go.
This is sad to hear. What a history.
I saw the Heath Brothers in Victoria, British Columbia, in about 1981. Jimmy played a scorching solo on "On The Trail", better than on the Riverside album of the same name, though that is a favorite of his albums. He was also very effective on Bags's Impulse album, "The Jazz 'N' Samba".
