John Barleycorn - Traffic (1970)
If you grew up in the 1980's, the Steve Winwood you hear on this recording is a different beast all together than the guy who sang "Don't You Know What The Night Can Do" on a Michelob commercial. This ancient ballad (dissected beautifully in its wikipedia article) is given new life by Mssrs. Winwood, Capaldi and Wood. Traffic, having just become a power trio after Steve returned from Blind Faith, crafted this lean, jazzy folk classic as the title song to their 1970 reunion disc. It is one of their finest moments. However, gems abound in their catalog, encompassing genre after genre. Most "progressive", to say the least.
So many versions, so little time!!!
