UPDATE - 6/29@5:29PM: The official Rush IG feed also posted a message alongside the same photo of Collins:
Peter Collins was our beloved producer for 4 albums. First on Power Windows ('85), then Hold Your Fire ('87), Counterparts ('93) and Test For Echo ('96). We loved seeing him in Nashville when we came through on tour. He had a mischievous, beaming smile and great sense of humour. He will be so missed.... RIP Mr. Big

According to an Instagram post from Alex Lifeson, former Rush producer Peter Collins has apparently passed away; Collins produced Rush's Power Windows, Hold Your Fire, Counterparts and Test for Echo albums. It's not clear when or how Collins passed, as there is no official obituary or news story posted online as of yet, but Alex posted the following message earlier today along with a photo of Collins (thanks Scott R):
Peter Collins will forever live in my memory as Mr. Big, sitting at his control centre beside a recording console with his ubiquitous tools: a legal pad, an ashtray and a Monte Cristo No. 2.
Love you B. Farewell.
