All I can say about the Wendal is what I was told. And admittedly, it was a number of years ago, but still I'm pretty certain about the conversation. Babylon Sisters was the song in question and I was told that Purdie's shuffle was recorded/sampled then replayed. And yes, WW is right. The reason for this was because of their search for a drum track played in "perfect" time. I'm not defending this...just passing along the info. Frankly, I don't mind tracks moving around a bit. But I remember at Porcaro's funeral stories told of him being constantly frustrated at his inability to play a fill in time! Those guys just hear things that don't bother me.
These guys weren't using a drum machine in the way we think of it. As I understood it, they had each guy show up, decided what to play, then and performed pieces of each song (kicks, back beats, fills, flams. Purdie's snare drags, etc) into the computer, then played it back. I think the hats and crashes were played live, but the drums were Wendal.
The process was nothing like a guy showing up with a drum machine and his sounds. Each tune was custom setup for the player and the song. Thus, the credits read as such.
No doubt Gaucho is a homage to Jarret at best...a bit of a rip at worst. However, to me, Jarret's tune seems to be a riff in search of a song. I guess that's why he couldn't sue them. The boys did borrow from time to time. There's an old Blue Note recording of a Horace Silver tune called Song For My Father they lifted. Note for note the intro is exactly the same on Rikki Don't Lose That Number. Still, they made a song out of it that's nothing like the orginal. Who knows which came first, the borrowed/stolen riff, or the actual song?
(I don't have the song, but if ya wanna hear the tune, here's a link to Amazon. It's on the album, "Best of Blue Note vol 1." You can scroll down and hear the tune from there)

Regarding Gaucho, I was such an Aja fan, when it came out, except for Babylon Sisters, I didn't really like it. However after a few years I figured it out. To me it was one of those albums that takes a while to open up. Maybe I wanted another Aja....Nightfly I liked right away, but only a few songs on that one still grab me the way they once did.
As for me, I love most of their stuff, Royal Scam, Aja and Gaucho in particular. I've heard the complaints about it being sterile. Well, sorry guys, I disagree. I think it's great music and it sounds great. Like any artrist, not everything is wonderful, but taking the body of their work, it's great stuff.
I do find it a bit amusing that some feel the need to jump in and pile on about how much they
don't like it. There are a lot worse albums that have been made. Those kinds of comments feel a bit like low-brow snobbery to me.
