No composer credits on release. The names in brackets on the center labels refer to the performers rather than composers.

On back cover of the release Nabil Totah is credited as the piano player and John Williams as the bass player. However it is vice versa. It is a liner error and corrected on credits list above. Kenny Dennis is most likely a pseudonym for recording reason for Kenny Clarke.
