They're available from Berkshire in a 20-CD set on the Art & Music label for US$39.80 played by Wolfgang Stockmeier. Normally, I'd say (and might still say), "It's Bach, it's under fifty dollars, what have I got to lose?" and spring for it. But aside from the dollar amount, which is a litle bit more than insignificant, I'm not sure I want to acquire 20 CDs in one swoop if the performance (or for that matter the organ) sounds disappointing. Does anyone have any advice based upon information or experience? I have never heard of Stockmeier. Does anyone know if this is a nice, crisp sounding organ or one that sounds like something from a small town movie theater? Should I buy or should I pass? Walter Meyer
