Information on an etude and a solo

[pjdicris]

Hello! In my studies I came across a set of etudes/routines called "Warmups from Hell" authored by Don Haddad, and a transcription of the first Marcello Suite trans. by Schule (instead of Don C Little). My usual paths for finding out about these two items proved ineffective, so maybe one of you came across either of these?

Let me know!

Best,
PJD

Thank you about the Warm-Ups information, the copy I found had "Don Haddad" at the top. Explains why I found no information on it!

It's a very poor photocopy I found in another etude book in the school library. It seems quite old.

It is handwritten. I was just curious because these warmups are VERY advanced, and where they came from
