Joe Maffei is getting back into the music business, and he’s doing it for his stepson.

The Waltham resident is putting on an all-day event Saturday, June 10, in honor of those affected by the opioid crisis that took the life of his stepson, Brian Nolette.

Maffei is organizing a screening of the movie "Beyond the Wall," which heavily features Nolette, at Embassy Theater on June 10 at 10 a.m., followed by four hours of live music at Garcia Brogan’s on Moody Street. Both events are free, but Maffei is hoping to raise money through a gofundme page as well as donations at the event. The proceeds will go to treatment centers Lowell House and Right Turn in Watertown.

"When my (stepson) died, I said, ‘I’m going to contact all my music people again,’" said Maffei, from his home in Waltham on Thursday, May 25. "I’m going to get back into the business and I want to solely get back into the business not as a promotion for myself or any money, but to raise money for the opiate problem."

Maffei was a drummer during the booming Boston music scene of the 1970s, and has plenty of connections with local musicians, including Aerosmith, which used to record at the Wherehouse in Waltham.

He hopes to use those connections to keep growing the event, and take it to other locations.

"I want to take what I’m doing here on a local level and bring it regional and then do something national. That’s the goal," he said.

Since "Beyond the Wall" was completed, it has been shown in various locations, including the Massachusetts State House.

The film deals with the struggles of ex-prisoners transitioning back into society.

One former prisoner, Louie Diaz, is the central figure in the movie. Diaz served 10 years in prison for stabbing a police officer while trying to flee a crime scene.

But upon his release, Diaz started working with people dealing with substance abuse, eventually becoming a substance abuse counselor for the Middlesex Sheriff’s office.

The film follows five men as they go through a reentry program, trying to make a living in the outside world.

Nolette, known to many as "Diddy," is one of the five men featured in the film. He died of a drug overdose in 2015.

"We was a tough kid," said Maffei, of Nolette, who spent many years of his life in prison.

Maffei said Nolette was turning his life around when he passed away, and was actually giving talks to others dealing with addiction issues.

Maffei has been heavily involved in fighting the opioid epidemic. In 2016, he was an advocate for a successful bill that repealed the automatic suspension of driver’s licenses of those convicted of a drug crime. In the past, the state automatically suspended the license of all drug convicts, adding an extra obstacle when they reentered society.

Transportation is a subject of personal importance for Maffei, who is legally blind, and was never granted a driver’s license. He saw a correlation with his struggle and that of recently released convicts who were not allowed a license once they got out of jail.

His ultimate goal is to start a nonprofit that would serve as a fund for those dealing with addiction to use for rides, essentially an Uber system for recovering addicts.

The system would work through a probation officer, said Maffei, and would help recently released inmates travel to various locations.

For the event on June 10, Maffei is hoping people who go to the screening of the film will take part in the live music event immediately after. While the subject matter of the film is heavy, Maffei wants the event to be a celebration. The day will also feature activities for children, such a face painting and a karate demonstration. There will also be tables where representatives from local organizations will be handing out information packets on opioid treatment.

"We’re not here mourning the dead," said Maffei. "We’re celebrating the living, the people who are in recovery, the hospital workers, the families of people who are struggling."
