"The fourth volume of Bear Family's seven-edition country-rock history Truckers, Kickers, Cowboy Angels: The Blissed-Out Birth of Country Rock kicks off with Commander Cody & His Lost Planet Airmen's locomotive rendition of "Hot Rod Lincoln," possibly the hardest-rocking cut yet featured in this series. It's a good indication of how things were changing in 1971, the year chronicled in this double-disc set. What began as a mellow breeze blowing out of Southern California grew grittier as it swept across the country, picking up musicians who were perhaps a little rowdier than the previous generation's".
