Funny you mention Marvin Cabell, Jim. I'd intended to write about him last night. (I was just too tired.) Because Cabell's sound really struck me too! It's an oddly compelling sound, "wrong" at times -- but in a Pee Wee Russell sort of way. Not precisely like Pee Wee, of course, but you know what I mean: Wrong but right. ... I did some poking around on the web, and couldn't find out much about Cabell. Apparently, he only appeared on ten or so LPs, and made just one as a leader (in the early-80s). But I did stumble across a reference to Cabell in Richard Cook's book, Blue Note Records: The Biography. Cook is in the process of trashing John Patton's album Accent on the Blues (on which Cabell appears) and in passing slams Cabell's playing as "wretched."
That made my eyes bug out! ... Just goes to show that you can't trust anybody's ears but your own. I suppose I shouldn't have been surprised because Cook dismisses EVERYTHING that Blue Note did in the late-60s and 1970s out-of-hand. Talk about painting with broad brush strokes! Way too broad, I'd say.
