Before going any further, I want to make clear where I'm coming from-- I'm actually a John Zorn fan who became interested in Patton due to his work with Zorn. I think this makes me a rarity in the Patton world, and effects my opinion of his work somewhat. Having stated that, I can talk about this record a bit.
Its hard to discuss songs on "Pranzo Oltranzista", because the emphasis is not on the songs, instead, its really on the composition or even the performance in many ways. The pieces themselves are rather diverse, everything from cello/piano interludes mixed with screaming sax and voice, purely sound effects, jazz-ish pieces, more noise oriented instrumental performances, pseudo-ambient, etc. What the album lacks is the sort of conventional formats-- there's no songs per se, no real structure in that sense.
But what there is really is worth looking into-- the album is filled with an abstract beauty, and while some of it may not make sense at first (or fiftieth) listening, like much of John Zorn's best work, rewards will become apparent with repeated listens. When I first heard this, I wasn't sure about it, but given the list of musicians (Erik Friedlander, Marc Ribot, William Winant, and John Zorn, among the most brilliant at their respective instruments) with Patton, I did devote an appropriate amount of time to it. I've found quite a bit on this record that is truly brilliant, be they as delicate as "I Rumori Dal Apertivo", or have the heightened anticipation feel of "Scoppioningola", or the beauty mixed with explosiveness of "Carne Cruda Squarciata Dal Sunno Di Sassofono", or just the delicate ambient beauty of "Latte Alla Luce Verde" and organized chaos of "Bombe a Mano" juxtaposed against each other.
Yeah, its nothing like Faith No More or Mr. Bungle, or Fantomas for that matter, and its even nothing like Zorn's work, contrary to many comments, but its a unique record with a lot to offer. Give it a try, if it doesn't set in, put it away and try again in a couple months-- I think with relative open-mindedness and reasonable diversity in taste of music, this one will make sense.
