On Capriccio. I hope they intend to continue with works of his that have received only one (or no) recordings of his (the couplings here, 2 fantasies for clarinet & horn, may not have been recorded, actually, not sure.) See Naxos distribution (https://www.naxos.com/catalogue/item.asp?item_code=C5381) (next month).
I think it's a third time for the Clarinet Fantasies too, just a second time for that with Horn (a terrific piece, by the way). For those who want to label their issues "first recording", I don't think there's any unrecorded Stanford chamber music left unless you start looking at arrangements of other things, such as Herman Sandby's transcriptions for cello and piano of 4 of the 5 Characteristic Pieces (originally for violin).
The existence of previous recordings has not prevented new recordings of Brahms, Dvorak and countless others and it is to be hoped that the same will go for Stanford, whose music can take a range of interpretative options.
or if they discover the lost violin sonatas :)
