While it's not quite the ultimate collection promised by the title, Deep in a Dream is still an excellent introduction to the music of Chet Baker. The 19 tracks, which were chosen by James Gavin, author of the definitive Baker biography, are culled from Baker's 1950s recordings for a variety of labels, including Pacific Jazz, Columbia, Colpix, Jazzland, and Jazztone. The tunes include both instrumental and vocal versions of Baker's trademark song, "My Funny Valentine," as well as a thoughtful selection of Baker's work with assorted groups, including Gerry Mulligan's famous pianoless quartet. Also included are previously unreleased a cappella versions of "Blue Room" and "Spring Is Here," which Baker sings in his fragile but compelling voice.
