I am a massive fan of Stuart Lingard from YBS at the moment. He has the sweetest sound, lots of vib but it never sounds out of control like others for me.
Another guy who is at the other end of the scale is Phillip Smith. Think he is now principal of the New York Phil, but was originally a cornet player with a strong SA background (his Dad was NYSB conductor for years). He still produces regular solo CD's and plays cornet on a number of tracks. His sound is so fat and warm but yet still bright (without the 'edge' that only a trumpet itself can give). I have a tape of him doing 'Song of Exulation' and it is immense, the very best renedition of it I have heard. He also recorded Ball's 'Glory to his Name' recently and it is so stylish, a real lesson in how to shape a variation solo.
Sure World of Brass will have some of his recordings if anyone wanted to hear more.
