When Sony released the splendid two-disc Essential Bill Monroe & His Blue Grass Boys in 1992, they opted to use alternate takes instead of better-known classic readings in a number of cases: 16 to be exact. While the inclusion of these alternates attracted some avid collectors who didn't own them, the omission of the official takes angered them even more. Thus, in 1996, Sony sought to rectify the situation by releasing this single CD with the 16 omitted official takes. Not only did this appease completists, it also made for a worthy single-disc introduction to Monroe's landmark recordings and his high-water band with Flatt & Scruggs. These songs are the very cornerstone of the genre. --Marc Greilsamer
