Xavier Montsalvatge (1912–2002) died less than 80 years ago. Consequently, his works remain under strict copyright protection in most of the world (typically life of the composer plus 70 to 80 years). This means that on public domain sites like IMSLP (Petrucci Music Library). Any PDF circulating on file-sharing sites is an illegal copy.
