LIPA invited the culture company to reveal its intentions for Liverpool Performs at the event on January 30.
It was felt that a celebration of the institute's remarkable achievements was the ideal occasion for such a launch.
The fame school currently has more than 1,200 students and is one of the biggest and most respected in the country.
It cost £15.8m to refurbish, which was raised from a wide variety of backers, including Sir Paul, who gave £1.2m, and includes a network of high-technology recording studios, control rooms, dance studios, rehearsal rooms, dressing rooms, visual arts and graphic facilities, classrooms, and a learning resource centre.
Joan Armatrading held a concert to support the Institute and has made regular visits since it was opened.
Guy Chambers, an official Lipa companion, Andy McCluskey, Thelma Holt and Nickolas Grace have all held masterclasses in their specialist fields.
Mark Featherstone-Witty, founding principal and chief executive officer of LIPA, said: "There are two themes to the event. We want to show the sound achievements we and the students have made and we want to look at the journey the students take from the first day they arrive.
"The people we have invited back are not just the glittering names, they are the people who have helped us and the people who
have become part of our history. This is all about the students."
Sir Paul is currently away on holiday and was last night unavailable for comment.
