Alex Lifeson plays on the title track of Big Sugar’s new disc, Eternity Now.

Gordie Johnson gives the details in one interview:

ME: How did the collaboration with Alex Lifeson of Rush come into fruition?

We’ve been pals for decades so all I did was call him. The title track ETERNITY NOW was heavily influenced by my love of Rush so it seemed like the time to make the call. I figured if he was involved I wouldn’t have to explain myself later. I asked him to play a guitar solo (he agreed) but he also sent a number of overdubs that made the song even Rush-y-er(?) He’s a total sweetheart and a mentor. We love Lerxst!

And also in another:

AC: I put the record on the other day and I thought I made a mistake. It sounded like I’d grabbed a Rush record from 1988.

GJ: [Laughs] Make no mistake, my friend. That was not an accident! [Rush guitarist] Alex Lifeson is on the title track. He’s on the title track of my life and career trajectory. He was one of the first supporters of Big Sugar and one of the greatest mentors that I’ve had. And he’s such a down-to-earth chill guy. He saw us coming up, liked our music, and would do things like “Hey, man, here’s a double-neck guitar. Why don’t you take the Xanadu guitar and use it for a while?” Like, who does that?
So I texted him and I had to explain myself because it’s such a Rush knock-off. I got the Taurus Moog pedals in there and gave it the full Moving Pictures treatment. But he not only sent me a wicked guitar solo but a bunch of overdubs–acoustic guitars and banjos and all kinds of other production to put in the track. It got way Rushier. And I’m good with it.
