T-bone, that Bis recording you mentioned is a terrific one. As a rule, the SACDs on that label are very good, as are most of the Telarcs. I forgot to mention the Ondine label, which does recordings of both the Philadelphia (live concert recordings)and Minnesota orchestras. There is a recording on that label of the Philadelphia Orchestra with Olivier Latry on organ playing the Barber Toccata, Poulenc Organ Concerto and Saint-Saens Organ Symphony that is excellent, and if you have a true full range system it will give you just about the most bass in the last octave (down to 16 Hz) that I've ever heard on disc.
