Costa Plays His Home Room at Mémoire the Night Before Halloween

Boston-raised DJ Costa, the resident at Encore Boston Harbor's Mémoire, plays Friday, Oct. 30, the night before Halloween.

The night before Halloween falls on a Friday this year, so a lot of Greater Boston will be out in costume a day early. At Mémoire, the nightclub inside Encore Boston Harbor in Everett, the man in the booth will be a familiar one: Costa, the club's resident DJ and a Boston native.

Costa plays Mémoire on Friday, Oct. 30. Encore lists the date on its own experiences calendar, calling him one of the top DJs in New England. The club is open Friday and Saturday from 10 p.m. to 2 a.m., and entry is 21+. Mémoire is at 1 Broadway in Everett, just over the river from Charlestown.

"Comes home" undersells it a little, because Costa hardly leaves. In our records he plays the Boston market more than anywhere else, more than 220 dates, and most recent ones are at Mémoire. His own site says he was born and raised in Boston and got his start on the radio at Kiss 108. He has held residencies at The Grand in Boston, and his site also lists Trio in Charlotte and Charleston.

A resident DJ is a different job from a touring headliner. Nobody is flying in to play one perfect set. The resident reads the same room week after week, knows when the casino crowd shows up after dinner, and has to keep a full floor going until 2 a.m. Expect current hits, throwbacks everyone knows and whatever gets the room singing. On a Friday when half the crowd will be dressed as someone else, that range matters.

The room suits it. Mémoire is a mid-size club, about 650 capacity in our data, built into a resort rather than a downtown basement, so it works as much for a birthday or bachelorette as for a dedicated club night. For a lot of people at Encore, Costa *is* the night out, and he plays it that way.

We didn't find a new Costa release tied to this date. This is about the night itself: a hometown DJ in his home room on one of the year's busiest nights out. If you'd rather spend Halloween weekend dancing than at a house party, Friday at Mémoire is a safe bet. Go early, check the dress code, and if you're wearing a costume, make it one you can dance in.

Dates and entry details are on Encore Boston Harbor's events page and the Mémoire page. Costa's bio and mixes are at dj-costa.com.
