Somebody has to be first for you. When I turned 20 and got zonked by Last Tango In Paris, I discovered my jazz raver for my rocker ears — “El Gato” Barbieri. I’m not as jolted by his death as several others this year, partly because he seemed like “an old guy” (an ancient 40) when I first heard him and partly because as I grew more familiar with more free jazz players, I realized Barbieri had limited ideas and range. I knew what was coming up before I heard it. I grabbed albums religiously for years (though I never much liked the over-orchestral Last Tango soundtrack). My eyebrows went up when I pulled out the vinyl from the basement and realized I had sold all but four LPs. My first pick would be the CD reissue that combines Bolivia (1973) and Under Fire (1971), my original favorite album (it’s on Bluebird, 2002). But the real find is his work with Don Cherry on Complete Communion (1966) before Barbieri had fallen into any of his later ruts. This is the one you gotta have.
