This is not a new article, but one I just stumbled upon with my Sunday morning coffee. A fantastic, informative read per WFMU's old "Beware of the Blog". My favorite tidbit is that the psych legend 13th Floor Elevators actually had some 45s distributed by Hanna-Barbera Records (after doing some more research, said 45 actually includes their first single and one of their most well-known tracks, "You're Gonna Miss Me").
And if you, like myself, saw the cover of that "Cattanoogacats" LP near the bottom of the article and frantically went searching for a copy ... don't. It is as rare (read: expensive) and you'd imagine.
