Benny played piano on Largo (after Piano Concerto No. 5 in F Minor, BWV 1056) by Johann Sebastian Bach on an arrangement for clarinet by Swedish clarinetist and conductor, Martin Fröst.  They were filmed together in RMV studios during the recording.  Largo was the only track on Martin's album and was released as a single.

Martin's album B.A.C.H. will be released on 24 October 2025.
