At 3:32 I was expecting the student to sing "Crazy little thing called love" (he sounds great though!). By the way, that clip with his son playing Haydn outside, the sound melt my heart.
That's an Eb Henry Selmer trumpet, with a Vincent Bach mouthpiece, Peter. That 1974 recording with Herbert von Karajan and the Berlin Phil is anthologic, you can find it on RU-vid. Take care, God bless you.
Did he play with "Farkas embouchure" like most classical students and was he only so talented that he could overcome the disadvantages of this embouchure type???
