I beg to differ with Latvian. The recording of the premi่re of Concerto di camera No. 1 is on the Canadian Music Centre website (performance identified as "Talivaldis Kenins. Conducted by Alfred Strombergs; world premiere, Latvian Festival concert, July 1, 1981, MacMillan Theatre, Toronto") and it is the same work as on the Ondine CD cited by Dave. A non-commercial recording of Kenins's Concerto di camera 2 can be heard in Miklos Pogonyi's archive:
https://archive.org/details/cd_canadian-composers_talivaldis-kenins_2, and on the Canadian Music Centre website, where the performance is identified as "Talivaldis Kenins. New Music Concerts ensemble conducted by Robin Engleman; premiere performance, Nov. 19, 1983."
