Wikipedia article (German)
An article on this festival in Neue Musik, 18Jg, August 1926 issue, notes that Ernst Levy's 5th symphony was given there along with the works by Ferroud and others noted at the ISCM website. Myaskovsky's sonata is mentioned on p.837 and it's suggested that Gieseking substituted for an indisposed Wührer, if my poor German is working right.
