Spanning five discs and well over one hundred tracks -- featuring all of the songs he cut for Capitol in the late '50s and early '60s, including alternate takes and unreleased material -- Leonard contains too much Tommy Collins for anyone but completists and historians. Nevertheless, it is the only collection of Collins' prime material to appear on CD. Collins was very influential and he deserves this deluxe box set treatment, but a single disc collection is needed -- it would make his music available to country fans that simply can't afford a box set of this magnitude, but still want to hear the singer. If you can afford Leonard, it's a worthwhile investment for dedicated country music fans, but there isn't enough first-rate material on the box to justify the expense for listeners that want to explore the roots of the Bakersfield sound.
