I always thought Creedence Clearwater Revival's eponymous debut LP was their best. Their cover of Dale Hawkins's Louisiana rockabilly hit "Suzie Q" was, in my opinion, one of the iconic tracks that established the genre of
acid rock. The long instrumental part, in a quasi-Andalusian modality that meandered yet eventually reached a climax, became a formula.
"Gloomy," also proto-acid-rock, was also a great tune but never made it into the "classic rock" canon.
They quickly found fame and fortune after releasing "Bayou Country" with the perennial Top 100 hit "Proud Mary." The fact that these kids, all of whom were Californians, were arguably the founders of the genre of
swamp rock (which is about the Deep South), is testimony to the fact that San Franciso was America's rock'n'roll center in the late 1960s.
Southern rock soon burst onto the scene with authentic Southerners like the Allman Brothers, Marshall Tucker, Charlie Daniels, Molly Hatchet and Lynyrd Skynyrd. But the genre has always attracted outsiders who perfectly mimic the originals. Alannah Myles, who sang the goosebumpy song "Black Velvet" about Mississippi and Elvis Presley, is from Toronto! Neil Young ("Southern Man," "Alabama") is also Canadian, as are all living members of The Band ("The Weight," "The Night They Drove Old Dixie Down"--the one American in the group, drummer Levon Helm, died last year).
