Back in the early 1950's the Selmer company produced two albums featuring two great trumpet players, Raymand Sabarich and Louis Menardi. The albums were produced to help demonstrate the Selmer trumpets. The playing and etudes in these recordings are just incredible. Has anyone heard these? They are refered to simply as "Etudes for Trumpet" on the album jackets. Does anyone know if the music to these etudes is available? Thanks!
