so far I've only heard your string quartet, but I'm definately going to take a look at your other works when time allows!
Firstly, you must be complemented on ur judgement of tone. I felt that you had set yourself an incredibly narrow range of harmonics (if that would be the most useful term to use) this being particularly apparent in the final mvmnt. In which respect I found the piece particularly rewarding. It's a highly 'concentrated' work in that regard which has however some remarkable shifts in colour (most notably the conclusion to the last mvnt. which has a real sense of having 'found' that quasi-Romantic tone).
I apologise if none of that made any sense, but expressing these things is remarkably difficult (perhaps that's why music is the better medium...!).
One comment though, is that I feel it could have easily been extended into a larger scale quartet with the sort of materials that were present. But perhaps its appeal may also b in its succinct nature...jus some thoughts for u!
