For some reason, I was late to jump on the Erskine train; of the major fusion bands, Weather Report is by a considerable margin my least favorite—which isn't to say they weren't great or didn't produce some great material, but I vastly preferred not only the Mahavishnu Orchestra and Return to Forever and Lifetime, but also The Eleventh House and even Tone and Brand X and Bruford. Oddly, it was the Peter Erskine Trio stuff, in the early to mid 90s, with John Taylor and Palle Danielsson, that really clued me in to just how great and versatile he is. (If you haven't checked out the series of albums they did together, I cannot recommend them highly enough—although you should know that Erskine decided to see just how quiet and restrained he could play with this band, so don't go in expecting pyrotechnics: it's gorgeous stuff, but not exactly the kind of barnburners he often did with Weather Report.)
So I'm rereading his autobiography, and he mentions touring with Steely Dan, writing:
I suspect that both Donald and Walter were hoping for a bit more jazz voodoo on that tour than I was willing to impart; the recorded drum parts seemed so perfect to me that I could barely stray from the original patterns and beats (though I would never claim to being able to play with the pocket and funk of mssrs Porcaro, Gordon, Keltner, Purdie, Marotta, and Gadd). All in all, a lot of fun to be part of a big rock-and-roll tour.
Which, on the one hand, he obviously fits in with that insanely august group just fine. And on the other hand, while it's not exactly news, sometimes it still hits you: holy cow, they hired most of the most amazing studio drummers of the time. That is a staggering collection of names.
So I thought I'd see if there were any videos of said tour on YT and there are! Over two hours of a show in the Bay Area. And of those two hours, about two minutes, total, seem to show a decent view of the drummer. Such is life. Still, whenever they do show Peter, he seems to be grinning.
