The attacker - described as black, with a shaved head and of medium build - then left the scene with the other man, who was Asian.
Ambulance crews rushed the victim to hospital, where he remains in a serious but stable condition.
His injuries are not believed to be life-threatening.
Police are now appealing for witnesses to come forward.
Detective Superintendent Howard Millington of GMP’s Bury District said: "This was a nasty, unprovoked assault on a young man who was simply out with friends enjoying himself.
"We’re pleased that he’s recovering well, but his injuries could have proven far worse.
"While we have limited descriptions of the offenders at this time, we believe there may be several potential witnesses to this incident, or people who saw the offender shortly before or after the incident.
"Were you in the Albert Street area at the time?
"Perhaps you saw two people matching our descriptions or have some information that can help us. If so, please get in touch as soon as possible."
Information can be left with officers on 0161 856 1063 or the independent charity, Crimestoppers, anonymously, on 0800 555 111.
