I got the Spring 2006 issue of the ITEA journal last week. Saw on page 30 and 31, writeups for these two pieces. Euphonium with piano acc. Just ordered them. Sure many have heard Arthur Lehman play The Devil's Tongue on the Art of Euphonium Playing records, but there is also a recording of him playing it a long time ago accompanied by a teen age girl on piano. I like that recording much more than the one on the record. Lots more energy, in my opinion, particularly the young lady playing it on piano.
Now, I am not saying that I can play either of these two pieces very well, but I am going to try!!!
