Yes, very much so.
I bought it back in the day thinking tht it was going to be a straight-up "Latin-Jazz" album (I was just beginning to discover the idiom for real) & was very disappointed that it wasn't. Traded it away within a month a forgot about it until the recent reissue. Revisited it and realized what a fool I had been to not pay better attention back then.
Long story short, the music is a very organic (as I hear it) "fusion" of Latin rhytmic elements, post-modal jazz harmonic elements, soling that is totally at home with the concepts of each, and an overall group dynamic that feels like everybody is on the same page. None of that mattered to me then because none of it was what I was looking for. But better late than never, right?
Also remember, if for no reasons other than trivia, that both Mantilla & Chambers were involed in M'Boom at the time. So who knows how much/what other stuff like this was coming out of that orb that wasn't documented? Maybe none, but it was a fertile time in a then-fertile place, and there was a fair amount of "cross-pollination" going on in general.
Along those same lines, there are two albums by some guy named Bobby Vince Panutto (sp?) from about the same time, maybe a tad earlier, that I didn't know about until a few months ago that have a lot of the same ideas tastefully brewing, as well as another one by Jorge Lopez Ruiz that's got both Steig & Gomez that's even more in the vein of the Matilla album, only moreso.
So yeah, check it out.
