Primus and Tool fans are in for a treat the September as Danny is set to fill in for Tim “Herb” Alexander for a few shows in September. Rolling Stone reports:

The drummer will be joining the bass-rumbling alt-rockers for their Riot Fest appearances in Chicago and Denver, as well as an after party at the Windy City’s Concord Music Hall on September 13th. Claypool reports that they decided to go through with the shows as a way to give Alexander some financial relief and that Carey was their top choice, since “we figured it would be hard to get [the Police’s] Stewart ‘Stew-daddy’ Copeland out of his ivory tower,” as Claypool joked.

As most of you already know, Herb suffered a heart attack not long ago and went under the knife for a triple bypass. He’s expected to be back behind the kit for the Primus tour in October. I’m sure most of you also know Herb drummed on the first A Perfect Circle album, as well as with Puscifer.

Danny also drops another Tool album tidbit:

As for Carey, he and his fellow Tool bandmates are currently working on the follow-up to their 2006 album, 10,000 Days. Although the group recently detailed for Rolling Stone the reasons why it has taken so long to make a new record – chiefly a lawsuit with an insurance company that keeps presenting new, time-sucking obstacles – Carey and guitarist Adam Jones reported they have written enough music for a new album but are editing it down to songs. “It’s all a little more ‘metal’ sounding, if I may,” Carey said at the time of the group’s direction. “I’m having fun drumming on it.”

It’s not the first time Les & Danny have collaborated by the way:
