"With her, she has a more structured background, which helps her do it even better and she has perfect pitch," Bowen said. "And for a musician to have perfect pitch, that's pretty special."
The group played at 9 p.m. after Massey's husband's band, the Jesus Rehab, and before local band Blind Man Leading.
A nanny by day, Massey grew up in Catonsville on Fairfield Drive. She graduated from Catonsville High School, then attended college in Boulder, Co.
She spent some time working on her music in New York City and, after talking to some friends living in Seattle, decided to pay them a visit.
"The way it happened was, I showed up in Seattle thinking I was going to be there for a month, literally with one bag and my guitar," Massey said.
"And I enjoyed my first month because of the music community there, that I wound up staying longer," she said.
"They said, 'You know, you're still making music. Why don't you move out to this notorious music city?'," Massey said.
From there, fate took control and led her to both her bandmates and her husband.
Her bassist at the time was also playing with the Jesus Rehab. He invited his bandmates to see Julia perform at her first big show in Seattle with him.
"And his bandmates actually turned out to become my husband and my brother-in-law," Massey said.
Her band consists of her, her brother-in-law, drummer Dominic Cortese, and Geoff Gibbs, who plays both bass guitar and electric upright bass.
Dominic Cortese also plays in the Jesus Rehab with his brother, Massey's husband, Jared Cortese.
"Within a year (of meeting each other) we were dating, and yeah we just got married last year," she said.
"We tour together, kind of 'Partridge Family' style," Massey said, referring to the 1970s television sitcom series.
The Baltimore show was the 10th of 14 stops on the group's "Age of Information Tour," which Massey said is its fourth large-scale tour.
In addition to Maryland, the tour brought them to Minnesota, New York and Illinois.
Massey did not linger long in Baltimore. The band left town for a May 4 show in Ohio and continues on the road to Minnesota before ending May 9 where it began, in Seattle.
Massey said she loves playing and touring with her husband.
"Music is our life," she said.
