I've had a track from this independently released album by John Too Cool McCool on my hard drive for a dozen years and just recently resurrected it. I've no idea where I got this pretty slick version of Mason Williams' hit Classical Gas as I don't own the CD and can't find anywhere that offers it as a download.
What can I tell you about the artist? Not much. He's from Mississippi, doesn't have a website but does have a Myspace page that hasn't been updated in years, literally. Much like the majority of that site, unfortunately.
McCool appears to favour electric blues judging by the sound samples at Myspace, unlike the earlier (2000?) pop-rock-R&B covers on 50 Years of Gold. In any case I like what he does with Classical Gas and you can get it below.
I can find no indication whether McCool is active as a working musician, although he does have a YouTube playlist of some of his music, including a crackerjack version of Ghost Riders in the Sky, which you can view below. It would be a shame if he weren't still playing live and recording. Let me know if you can shed any light on the matter.
