This morning, two pairs of hands belonging to Sivan Silver and Gil Garburg danced across piano keys in the KPBX studio. The Silver-Garburg Duo came to the station to discuss their return to the city to feature in the Spokane Symphony’s upcoming “Classics 4: Sibelius & Brahms” concert, performing an arrangement of Brahms' famous Opus 25— the lyrical and passionate First Piano Quartet— with four hands on one piano. The performances will be at 8 PM on November 3rd and 3 PM on November 4th in
