When asked how many bands will be performing at this year’s LadyfestMV on Saturday night, co-founder Rose Guerin answered: “A million.”

She also allowed that math isn’t her best subject.

But if excitement can be measured in exaggeration it can also be measured in good deeds. This marks the fifth year for LadyfestMV, a combination block party and music festival on Circuit avenue in Oak Bluffs, and awareness builder and fundraiser around the issue of domestic violence.

The event was created in 2017 by Ms. Guerin and Kelly Feirtag, who manages the Ritz.

“When we started doing this we wanted to have a reason behind it,” Ms. Feirtag said, recalling the origins of what has become an annual female-empowered rite of fall.

“We both feel honored that we have been able to partner with CONNECT,” she added, referring to CONNECT To End Violence, a division of Martha’s Vineyard Community Services that is both a domestic violence program and rape crisis center.

“CONNECT is under a big strain this year with domestic violence on the rise during the pandemic,” Ms. Guerin said. “It is important to get the message out that there is a place to turn to.”

To that end, there will be awareness booths at the festival, along with voter registration tables.

The music begins at 5 p.m. on Saturday. In preparation, Circuit avenue will be closed to vehicle traffic beginning at 3 p.m. that day.

Last year the celebration had to go virtual and organizers said they were initially worried it might have to be virtual again this year. But when they approached their board and town officials, everyone agreed, they said. The show had to go on: live.

“We are now an official nonprofit,” Ms. Feirtag said. “We have a board and went to them and they said definitely, and the town said definitely, too.”

The event features numerous bands (slightly under a million) in various iterations, with a big stage outside the Ritz and a smaller acoustic stage by Post Office Square. In addition to the music, there will be food.

“Tons of food, with chefs from all over the Island doing pop-ups,” Ms. Guerin said.

Restaurants, bars and shops will be open, too, and masks will be available for those who want them.

And after all the organizing she has been doing, Ms. Guerin is excited to perform live on Saturday, both solo and with friends.

“There is nothing like the big stage and playing outside,” she said. “A lot of people can’t go indoors and there’s a hole in their heart not seeing live music. But this will be safe.”
