Like many Rhino compilations, this is geared more to the novice or the casual fan than the aficionado, but that's not a criticism. If someone wants a basic primer of the bluegrass sound past and present that manages to be accessible and avoid unduly clichéd track selection, this 18-song compilation fits the bill well. Most of the biggest names are here (Bill Monroe, Flatt & Scruggs, the Dillards, the Stanley Brothers, the Kentucky Colonels, J.D. Crowe, Ricky Skaggs, Alison Krauss), as are some of the genre's top standards ("Blue Moon of Kentucky," "Orange Blossom Special," "Uncle Pen," "Foggy Mountain Breakdown"). The inclusion of Flatt & Scruggs' "The Ballad of Jed Clampett," Eric Weissberg and Steve Mandell's "Dueling Banjos," and the Nitty Gritty Dirt Band's "Will the Circle Be Unbroken" may rankle purists, but it clears the path to listeners who are only familiar with the idiom through these songs, and may find a lot more that they'll like on the less overexposed performances on this anthology.
