Below are profesional oboe players to listen to.
Heinz Holliger, John De Lancie, John Mack, Harold Gomberg, Ralph Gomberg, Marcel Tabateau. It is better to stay away from European performers (other than Holliger) as their school of thought on tone is very different than ours. Composers and standard repertoire: Mozart (concertos, sonatas, and quartet with strings), Poulenc, Hindemith, Handel (sonatas concertos and concertos for 2 oboes and continuo), Vivaldi, Telemann and Britten. Specific recordings of interest: any Holliger or De Lancie recording; The Art of Oboe Playing (Tabateau) - includes performances and discussion, may be out of print; The Gift (Nancy Rumbel with Eric Tingstad) - a Christmas album with lots of solo oboe and English horn.
