I love the degree of control you wield over your material, Matt. Particularly with regards to harmony. I can't say I was a fan of the gliss.'s because in my mind it detracts from this overall feeling of precise control. But it's a small quibble.
The cadenza is interesting and just generally well put together. Those disjunct lines are a world apart from what I'd normally write, but they still "work".
My impressed-ness is veiled with a thin layer of commissioned criticism here.
I haven't got much else to say, other than good job as per usual.
May I ask how you got the performance, purely out of interest? Are they people you know?
