Creedence Clearwater Revival, with the Eagles, are often regarded as America's answer to the Beatles. CCR and the Eagles are also, in some regards, rivals within the Country music community. As the "Big Lebowski" movie perfectly illustrated, both bands represent different schools of musical thought within the specter of Country music, determining whether one prefers raw, powerful, roots-based tones or just simple, feel good songs(this is the best way I know how to condense these thoughts). Personally, I think CCR ties more into Southern Rock than they do Country. The Eagles aren't so easily pinned down--They are truly in a place all to themselves, musically.
In 1969 alone, the band scored hits with "Born on the Bayou," "Proud Mary," "Bad Moon Rising," "Green River," "Lodi," "Down on the Corner," "Fortunate Son," and "The Midnight Special." While none of their songs ever scored higher than #2 on the charts, they have achieved far more airplay in the 44 years since their breakup than have most #1 selling bands.
These two are my particular favourites...
