There is no shortage of excellent John Denver compilations, and RCA Legacy's two-disc Essential John Denver collection doesn't disappoint.
All of the hits are here ("Rocky Mountain High," "Calypso," "Back Home Again," "Annie's Song," "Perhaps Love," etc.), and the sequencing is linear and concise.
Fans looking for a more diminutive yet equally satisfying overview should check out 2005's Definitive All-Time Greatest Hits, but for the discerning listener looking to capture the full scope of the late country-pop great, this rich slab of history will more than suffice.
