It sounds like 9/26 is an entire session I do not have, so the 2-CD set is worth acquiring since I only have the Hilversum session. That is exactly what I was trying to figure out, if there was any other material elsewhere.
Curious as to why the 9/3 date was not included in the 2-CD set.
So, to summarize, a hypothetical complete Ayler/Cherry box would include:
New York Eye And Ear Control
Vibrations/Ghosts
Hilversum Sessions
Jazzhus 9/3/64
Danish Radio 9/10/64
Jazzhus 9/26/64
There are probably more recordings that have not surfaced...
Update:
OK, looking at the Revenant Box, which gives 9/3 as the recording date for Jazzhus, the track list is the same as for the 9/26 session and the timings are all very close (Saints is listed as Tune Q).
I am pretty sure these are the same session, in which case the CD I need is the 9-track single CD on Hatology.
PS: They are also both sidemen on the 11/17/65 Sunny Murray session. Not a big fan of that one.
