Sorry....that was meant to read 'Tone depth of GPO player'.
I have been struck with the variation of tones available from (GPO) orchestras in general as there happens to have been recent juxtaposed postings with strongly contrasting orchestrations.
I'm thinking of bmonroney's Isoldens Liebestod (glad you posted that as it is one which I haven't heard before but greatly enjoy now), Darwinkopp's Rimsky-K, Trent's Vivaldi Spring, Nicole's Mozart and Karl's Vivaldi Guitar concerto not to forget the earlier Thus sprach Zaruthustra, and there are others that I've left out I'm sure (apologies).
I know this is attributable to the composers, conductors and musicians; but isn't it marvellous (again) that, with a few month's practice using GPO (a $250 'programme'), such realistic renditions can be produced! GPO definitely has the breadth and depth to rise to the occasion and deliver a sufficiently varied selection of instrument tones and articulations to deliver the goods.
It's also noticeable how others are catching up (caught up?) with with the wonderful first MP3s which sold more than a few copies of GPO, I'm sure.
