With Halloween on a Monday this year, we have an extra day for things going bump in the night.

To get you started, here are some of the doings doing for Halloween this weekend.

Friday

Ghosts at Under Glass at the Domes: Spooky fun for the whole family at the Mitchell Park Horticultural Conservatory, 524 S. Layton Blvd. Ghosts Under Glass starts at 6 p.m. Friday, trick-or-treating, a Halloween carnival and crafts. Kids receive a pumpkin and candy with admission: $8 per person, free for children 2 and younger. Tickets can be purchased on the Domes’ website.

Steampunk at the art museum: Travel to a time when steam power was king at MAM After Dark: Steampunk Friday. Dress in your steampunk-inspired gear, explore the new exhibition, “Haunted Screens: German Cinema in the 1920s” and hear music from Buffalo Gospel and Radio Milwaukee’s Justin Barney. Quasimondo Physical Theatre will perform, too. Admission is $10 in advance and $12 at the door.

Mad Planet Halloween Retro Dance Party:The Riverwest club, 533 E. Center St., is gloriously gaudy all-year-round, but for Halloween, it really goes all out. And so do the club’s dancing clientele, who sport imaginative attire for a shot at the costume contest grand prize (this year it’s $150 in cash). The party starts at 9 p.m. Friday; cover is $10.

5th annual Best Place Halloween Party: 9 p.m. to 2:30 a.m. Friday, Best Place at the Historic Pabst Brewery, 901 W. Juneau Ave. There’s a $5 cover, with a free barrel of Pabst Blue Ribbon to kick off the night, and free pizza at 11 p.m. Also: prizes for best costumes.

Gloss Records Halloween Spooktacular (also Saturday): The local DIY record label’s become such a leading force in town, this will be its second multiday, multivenue fest in six months. Night one Friday at Cactus Club, 2496 S. Wentworth Ave., features (in order) local rock acts Sex Scenes, Surgeons in Heat, Rio Turbo and Soul Low. The second night Saturday, at Riverwest Public House Cooperative, 815 E. Locust St., includes Moon Rats, Piles, Soup Moat and NO/NO. Each show costs $7 at the door. Both shows start at 9 p.m. and feature a costume contest and raffle.

Saturday

Halloween on Brady Street: Fourteen bars and restaurants on the nightlife strip Saturday are holding costume contests, with each picking a winner to compete in a grand-prize drawing ($1,000 to the winner) at midnight at Nomad World Pub, 1401 E. Brady St. For participating night spots, go to bradystreet.org.

Bryant’s 007 Halloween Party: 8 p.m. Saturday, Bryant’s Cocktail Lounge, 1579 S. 9th St. Bryant’s goes 007 with a spy-themed Halloween.  Dress as James Bond or your favorite Bond character. There’s a $5 charge at the door, with Bond-themed cocktails all night.

Vanguard’s Halloween: Last year, sausage-and-whiskey purveyor the Vanguard changed its persona to a Chinese-American restaurant for a night to try on a different cuisine. This year, it will explore the concept of a seafood shack called Hook, Line & Sinker for a night, starting at 5 p.m. Saturday. Co-owner Jim McCann said the Vanguard will close at 2 p.m. that day and reopen redecorated at 5. The menu and prices were still being finalized, but the lineup will include lobster, crab and shrimp with hush puppies, soup and poke. The bar will have two draft cocktails mixed for the occasion, likely rum-based, McCann said. Seafood will be served until 10 p.m. or until it runs outs; the Vanguard is expected to revert to its regular menu afterward for late-night.

Lazy Susan Halloween gala: Lazy Susan, 2378 S. Howell Ave., is throwing its annual Halloween party on Saturday with a buffet, magic show, tarot card and palm readings, costume contest, karaoke and a DJ. Doors open at 7:30, and the buffet featuring roast goat starts at 8. The ticket price also includes one Halloween brew. Tickets are $15 in advance with a donation of nonperishable food items for the Bay View Community Center Food Pantry; tickets can be bought and the food dropped off at the restaurant. At the door, the price for the Halloween gala will be $25.

Nightmare on Center Street II: Four Center St. venues — Company Brewing, the Jazz Gallery, Club Timbuktu and High Dive — join forces for this second annual event Saturday, hosting 16 acts (the Fatty Acids, Chalice in the Palace Soundsystem and Chakara Blu among them); a costume contest with a $300 grand prize; and a Halloween-themed late-night menu at Company Brewing. There’s also a screening of the 1915 silent film “Alice and Wonderland” with newly composed accompaniment by DIY Chamber Music Presents.

Tickets and more info are at brasstapbeerbar.com/greenfield.

Talking Heads Halloween Party: As the annual “Stop Making Dance” dance party at the Milwaukee Film Festival shows, this town really loves Talking Heads. (Shorewood’s own Jerry Harrison, after all, played guitar and keyboards in the band.) But you don’t need to wait until next year’s fest to don your best big suit and get freaky to “Burning Down the House.” Saturday’s show at The Gig, 1132 E. Wright St., features three sets of Heads covers. The show starts at 10 p.m., the cover price to be determined.

Linneman’s Halloween Covers Show: You’re never going see the real AC/DC, the Coasters, ELO and Weezer at the same concert, but you can see members of Milwaukee bands Midnight Reruns, Sat. Nite Duets and more dress up like those seminal bands and cover their tunes. Admission for Saturday’s 9 p.m. show at Linneman’s Riverwest Inn, 1001 E. Locust St., is $7.

“Hal-Lit-Ween”: Wisconsin author Stephen D. Sullivan and the performance duo Maya Kuper and Paul McComas join forces Saturday for a party and fundraiser for Woodland Pattern Book Center, 720 E. Locust St. Suggested donation is $5; the program, including scenes from the McComas/Sullivan collection “Uncanny Encounters — “Live!: Dark Drama, Sci-Fi Screams & Horrific Humor,” starts at 7 p.m.

Monday

Riverwest FemFest Halloween Ball: For two years, Riverwest FemFest has shined a spotlight on the diverse and talented female artists in the city, and raised money for the Milwaukee Women’s Center and Date Rape Awareness Milwaukee. Aspiring to go even bigger for its third installment in January, this four-band fundraiser, with New Boyz Club headlining, also has live painting and a costume contest. The cover is $5 for Monday’s 9 p.m. show at Company Brewing, 735 E. Center St.

The Official Houdini Seance: Escape artist and illusionist Harry Houdini, who grew up in Appleton, died on Halloween in 1926. This program, including discussion of Houdini’s life, magic entertainment and live music, continues the tradition of holding a seance to attempt to connect with him. It starts at 6:30 p.m. Monday 10/31 at the Landmark Oriental Theatre, 2230 N. Farwell Ave. Tickets are $15.
