Bill Charlap and Renee Rosnes are two of the best jazz pianists in the world. And they’re married. So when they decided to perform together at the Stanford Jazz Workshop, they had a tough compromise to make: Who was bringing the rhythm section?

Bassist Peter Washington and drummer Lewis Nash are the beneficiaries of this decision. But so are you, as together, Renee and Bill have been playing with Peter and Lewis for well over a decade; this is going to be one heck of a great show! The performance is Saturday night at 8 p.m. in Dinkelspiel Auditorium on the campus of Stanford University, and you can be there for free!

Just be among the first 10 people to answer this question correctly: From whose trio did Peter Washington and Lewis Nash come originally, from Bill’s or from Renee’s?

The winning answers must be correct for both Peter and Lewis!

Email your answer to [email protected]. Winners will be notified by return email. Tickets will be held at Will Call on the evening of the performance, on July 9. Box office opens 1 hour prior to showtime, at 7 p.m.

Good luck!
