[Brahms] “recordings are excellent, Grumiaux’s playing and interpretation equal any I have ever heard . . . balance between soloist and orchestra is natural, no praise is too high for interpretation - a most lyrical performance, full of beauty"

" [Mendelssohn] “these performances are among the best and Grumiaux’s playing has his usual purity of style and instinctive musicianship to commend it.”

[Corelli] : “a glorious tone, and he infuses Corelli's beautiful slow movements with warm lyricism ... difficult to resist such beauty” (all: Gramophone)
