If you go by precedence, Maynard James Keenan's two-band involvement at the River's Edge Music Festival this weekend bodes well for the ambitious new fest on St. Paul's Harriet Island.
"The last time I did this was the very first year of Coachella," he said of the California mega-fest that is now one of the nation's top music events.
Keenan's visionary prog-metal quartet Tool booked its only show of the summer (and probably the rest of the year) to headline Saturday's opening day -- a rare convergence that came about because the enigmatic frontman already planned to be at the festival with another of his bands, Puscifer, which performs Sunday.
Keenan, 48, is the main tool that River's Edge promoter Live Nation is using to draw out-of-towners for the event's inaugural year.
He remembers his last twofer weekend in 1999, when he debuted yet another band in the desert southeast of Los Angeles: "The very first act that ever played Coachella on the main stage on the very first day of the festival was A Perfect Circle. And then the next night Tool closed the show."
Reached by phone in Los Angeles last week as Puscifer prepared for its tour kickoff at the country's biggest music fest, Bonnaroo, the Detroit-bred hard-rock vet and newfound winery operator offered sage advice to organizers of River's Edge.
However, getting Keenan to talk about the band that made him famous -- and is earning him a big paycheck Saturday -- proved difficult. Asked at the start of the interview about the quartet's otherwise dead schedule, he curtly replied, "You must be talking about Tool. I'm talking about Puscifer. We're on tour all summer, promoting our second album, 'Conditions of Our Parole.' "
Here's how the rest of the conversation went.
