Thursday's event -- held at the same place where four of the five victims died -- was all about giving back. Brown Paper Tickets introduced special artist tickets for upcoming events in Seattle and around the country, and proceeds from each ticket will benefit victims' families.
Jimmy Berg of Brown Paper Tickets was friends with two of the victims and organized Thursday's event.
"I feel like we're doing justice to their memory and I think celebrating and trying to move on from the mourning, but it's still very painful,' he said.
In May, the caf became the scene of a deadly shooting after Ian Stawicki opened fire on five people, killing four. Among those killed were musicians Joe Albanese, Drew Keriakedes, Don Largen and aspiring actress Kim Layfield.
"When somebody dies it's such a reality check, it puts things into perspective," said Lauren Imbrock, who was friends with the victims.
After leaving Caf Racer, Stawicki then opened fire on Gloria Leonides while stealing her car. He eventually shot and killed himself.
"It created an awareness of while you're in a public space there's a possibility there could be violence and you could be harmed," Imbrock said.
Despite the tragedy, locals still feel safe at the cafe. They returned on the six month anniversary to pay tribute to the victims and celebrate their lives.
"They loved playing music and they were always -- whenever we played music together -- they were always the people I wanted to hang out with, because they were so excited and positive about it," Berg said.
The limited edition artist tickets cost 25 cents extra, and if they all sell it will raise $25,000 for the relatives of the victims.
