One of the interesting things to me about Sorabji's music, which I have been listening to for about twenty years, is that we are seeing it so gradually and patiently exposed to view, rather like the faces on Mount Rushmore.
When I started listening to Sorabji there was only really Ogdon's Opus Clavicembalisticum on CD, which is not a particularly good starting point for a new listener. There were some short works, including those Altarus "single-work" discs, and the Organ Symphony No. 1 (which, personally, I still find incomprehensible today) but it took years for it to become clear that there were depths of fine works in Sorabji's ouevre other than O. C.
The idea that we would need a full performance of O. C. in order to persuade a skeptic is now absurd. We have Toccata No. 1 or the Concerto Per Suonare Da Me Solo (both single-disc works), as examples of substantial works of moderate length. We also have short works; if a new listener cannot be persuaded to sit through more than three or four well-chosen examples of the Transcendental Studies, then perhaps Sorabji is not for that listener. The length of the works is therefore no longer an insurmountable obstacle to appreciating Sorabji. (It's also probably true that we should stop vaunting the length - or underperformed status - of Sorabji's works as though that were, in itself, a merit!)
I understand that some of hostility to Sorabji in this thread - and to Finnissy in the thread on the most difficult piano piece - is a knee-jerk reaction to the supposed elitism of these composers (or, more properly, the elitism of their fans) but surely we are at a point now where Sorabji can be considered objectively alongside other composers, rather than regarded as as some arcane extreme.
