The photo is of the excellent Dr William Lovelock standing outside Trinity College London.
He is the author of the fine textbooks I use on this site. And TCL is where I did my Flute LTCL when I was a student.
All the exercises from this book are complete, but are still in manuscript. I will put them into Dorico bit by bit and make any improvements as I go.
When Chapter 2 is finished (Chaper 1 is a pep talk, and already available to see on this site), I will upload it and then most likely make mockup recordings using Dominus Pro Choir.
