One stage, one night, ten of the most accomplished pianists in the world performing music we all love—from Classical, Jazz, New Age to Pop Contemporary– arranged by brilliant composer and musician Michael Allen Harrison.  Ten Grands has thrilled audiences in sold out concert halls for 15 years and was created to be a platform to support music education. Ten Grands creates opportunities to cultivate the talent of the next generation and deliver the message on how music is one of the most important pieces of a complete education.  Awe-inspiring guest performances from young musical prodigies astound and delight throughout this enchanting two and one-half hour musical feast that is one of the hottest entertainment tickets in the Northwest.  And now we are bringing these thrilling performances to venues around the country.

Bring the show to your town… 


The Ten Grands model is simple:  A non-profit show with proceeds going to the local community where the show is performed.  More than $2.5 million has been raised in the last 14 years to benefit music education in schools and other youth and community programs in the Pacific Northwest.
