2 very interesting organ discs:
1) J S Bach - The Four Great Toccatas and Fugues,
The four Antiphonal organs of the Cathedral of Freiburg
E Power Biggs
Available on either CD or MCH SACD, this was a mid-70's Quadraphonic recording that has been remastered for 5.1 SACD. Can only be described as stunning in 5.1 on SACD. This cathedral has 4 huge organs installed in different locations, all controlled by a central console and played simultaneously. Makes an astonishing surround effect with a different organ in each corner of your room.
2) "Funky Organ: B3 Jazz Grooves"
In spite of the title, this stereo SACD Hybrid is worth the low cost for any B3 fan. Excellent SQ
