but on Acte Préalable this time, not Guild, so not Volume 2 exactly. Don't know if Guild's CD was meant to be volume 1 of a set anyway. No overlap with the other CD either, though, it seems.
MDT mentions (http://www.mdt.co.uk/huber-hans-works-for-violin-marucha-agnieszka-tomasz-acte-prealable.html) a recording of Huber's violin sonatas nos. 2 (op.42 in B-flat, pub.1879) and 7 Graziosa (Op.119 in G , pub.1903) along with at least some of the Poetische stücke Op.99 (pub.1888).
So, now we have CD versions of No. 1, 2, 5, 6 and 7 of Huber's Violin Sonatas?
