Northwest BachFest December Classics You either love it or you hate it, but classical music is called “classical” for a reason. Northwest BachFest Live is back with two special December performances. The first concert, on Dec. 11, includes music from the 19th and 20th centuries when piano music was just starting to become mainstream. The second, on Dec. 12, showcases diversity, anniversaries and virtuosity. From musical masterpieces to rare gems, the soloists at these concerts present their virtuosic excellence and honor classical musicians all throughout time.
