Cohen chose the selections, drawing more than half of the 31 tracks from three landmark albums--his 1967 debut Songs of Leonard Cohen, 1988's I'm Your Man, and 1992's The Future--along with four from 2001's Ten New Songs. The collection justifies its title as deep as it goes, though it's a shame that Cohen's commercial profile couldn't justify the more elaborate box set his artistry warrants (one that would at least include lyrics and musician credits). Those who sample the consistently inspired music here might come to the conclusion that everything Cohen records is essential. --Don McLeese
