After October’s sold-out opener for Vashon Allied Arts Chamber Music Series, it’s time for the second concert in the series, scheduled for 7:30 p.m. Friday and Saturday at the Blue Heron.

This concert will feature an all-women ensemble of players invited by acclaimed Island cellist and series’ co-artistic director Rowena Hammill to share the stage.

The quartet will play a repertoire that includes a violin/viola duo by Martinu, Mozart’s divine Divertimento for string trio and Schumann’s E flat piano quartet.

Guest musicians include violinist Victoria Parker, pianist Cristina Valdes and violist Heather Bentley.

Parker performs with Seattle Symphony and Seattle Opera, and can also be heard  playing on many albums and film soundtracks. Her love for collaboration and interest in interdisciplinary arts helped launch Gossamer, Parker Duo and Helix Series. She holds degrees from Western Michigan University and Manhattan School of Music.

Valdes is known for presenting innovative concerts with a widely varied repertoire. She has performed in Lincoln Center, Carnegie Recital Hall, Nordstrom Hall and the Kennedy Center as well as with the Seattle Chamber Players, Mabou Mines Theater Company, Parsons Dance Company and others. Festival appearances include the Singapore Arts Festival and Brisbane Arts Festival. She currently teaches piano at Cornish College of the Arts.

Bentley, a member of Odeonquartet who is on the faculty of Seattle’s Northwest School, has been a fellow and principal violist at Tanglewood Festival and associate principal of New York String Orchestra. She has also performed solo with Pacific Northwest Ballet Orchestra, Northwest Sinfoniettaa and San Francisco Conservatory Orchestra. Regional performances include the Seattle Chamber Players and Olympic Music Festival.

Tickets to the concert, $18 and $21, are on sale at Blue Heron, Heron’s Nest, Vashon Bookshop and www.brownpapertickets.com.

Both concert evenings will offer the same repertoire and players.
