Asleep at the Wheel more or less can be defined as an ongoing tribute to the western swing music made famous by Bob Wills & His Texas Playboys. It is a generational band in which players are expected to come and go over time. Of course, many rock bands have become the same thing due to their unexpected longevity. It seems part of Asleep at the Wheel’s overall strategy rather than something that happened by accident, however.
Wikipedia added the genre developed in Texas, Oklahoma and California in the late 1920s. It is an up tempo mix of jazz, rural and cowboy music, polka, folk, Dixieland and blues.
In other words, it is deeply American music. Bob Wills & His Texas Playboys is the best remembered western swing band. Others, according to Wikipedia, include some great names: The Light Crust Doughboys, Milton Brown and His Musical Brownies, Spade Cooley and His Orchestra (who I believe Ed Norton gave a shout out to in an episode of “The Honeymooners”) and Hank Thompson And His Brazos Valley Boys. The article adds that The Hot Club of Cowtown is a current western swing band.
The discography at Wikipedia lists 32 albums, eight current members and 33 alums for Asleep at the Wheel. The band was formed in Paw Paw, West Virginia in 1969 and played the rock circuit: Early on, it opened for Alice Cooper and Hot Tuna. Five years later – supposedly at the suggestion of Willie Nelson – Asleep at the Wheel moved to Austin, Texas. The profiles note that Van Morrison was an early proponent and that the band got important help from Commander Cody & His Lost Planet Airmen.
The bio simply is too long and exhaustive to dive into. It covers decades and features a small army of people, a lot of albums, a lot of guest performances and a lot of changes.
AllMusic credits “The Wheel,” as Steve Huey (and probably others) calls the band, with keeping alive and updating western swing, which is an enjoyable and important music. It’s a big band, Huey writes, usually featuring 11 to 13 players. So far, it has released three albums directly celebrating Bob Wills. All the others most likely are indirect tributes.
