Scalatron live in '75 -- was it JI?

Hi everyone!

In case you haven't been following the MMM list lately and would like
to play "guess the tuning", then take a few minutes to listen to this
recording of a live performance that I gave in 1975 on the Scalatron,
which Carl Lumma generously offered to host on his website:

Is it a temperament or JI? (The filename offers this clue: it's an
improvisation in a 29-tone tuning.)

Afterwards, you can read all about it here:

Enjoy!
