Virtuoso pianist and Washington native Stephen Beus will join Kairos (Carrie Rehkopf and John Michel), Brendan Shea and Michelle Rahn to perform the riveting piano quintet by Brahms. The 6 pm concert time is intended especially to encourage families to attend. The program will be repeated at 7:30 Thursday night at CWU. These performances are made possible by a grant from the Ellensburg Arts Commission.
