As a rule, record companies don't give artists the chance to pick the songs when a boxed set is assembled. They might ask the person who writes the liner notes to interview the artist, or they might even have the artist write the liner notes. But the label, not the artist, usually chooses the material. Self Portrait is an exception; when this five-CD, 95-track boxed set was assembled in 2001, a 91-year-old Artie Shaw was given a rare chance to make the selections himself and comment on them. And for those who are seriously into the clarinetist, it is fascinating to see what he chooses. Self Portrait, which spans 1936-1954, contains most of his essential swing, era hits, including "Stardust," "Begin the Beguine," "Frenesi," and his ominous signature tune, "Nightmare."
