There is J.S. Bach organ extravaganza going on in the Chicago area now. Sonya would have attended all ten concerts!
Almost 30 organists are playing a total of 256 organ works. From the shortest chorales and chorale preludes, to the largest, like the toccata and fugue in d, it's going to extend over 30 hours.
CDs are going to be made available for $80 (!)
