Straz Jazz Project: Michael Ross Quartet w/Fred Johnson This iteration of the first-rate unit includes pianist Pablo Arencibia, drummer Josh Platt and David Pate, the dean of Bay area saxophonists. The concert will consist of the foursome playing Ross originals; nonpareil vocalist Johnson joining in for a few standards; and some intimate duets between Ross and Johnson, a format that the two long-time cohorts have been exploring for a few years now.
