Women’s roller derby has begun to skate along the line of mainstream with the recent slew of media attention it’s been receiving (Whip It, whip it good). But anyone who wants to argue that roller derby is a just  another passing fad might have a knuckle sandwich coming their way, served up by the delicious Derby Dolls.

This Saturday night, coming to you live from the ground zero itself- the Doll Factory- the undefeated Swarm will take on the Tough Cookies, the defending champs. What better way to unwind from a hard week than kicking back, cracking open a cold one, and watching girls put the fatal in “femme fatale”?

The event poster reads: Full-Contact Action at Breath Taking Speed, The Greatest Sport of All Time, A Battle of Epic Proportions! And you better not argue with them. It promises to be a swift kick to the groin of a good time and a night filled with girl on girl action.

General Tickets are $17, VIP Tickets are $40

The Doll Factory- 1910 Temple St., Doors open at 6 p.m., 21+ only

Are you tired of going to Halloween parties  full of people who think they’re too cool to do the real monster mash? 

If your answer is ‘yes,’ dump your left-footed friends and head down to the LA Sports Arena on Halloween night. It’s time to find your glow sticks, suit up in spandex, and dance the night away with 65,000 of your closest friends. It’s the 12th annual Monster Massive — a frightfully fun night/early morning full of electronic music, light shows, and intricate costumes. The second biggest event in the raver calendar (topped only by the Electric Daisy Carnival in June), this year’s line up features the likes of Armin Van Buuren, Felix da Housecat, and Crystal Castles plus a host of other electronic djs to fill your dancing shoes’ needs.

Tickets are $70 (plus taxes- Ticketmaster always manages to get you where it hurts) but the ticket pays for the quality of the event. The LA Times has said, “If you’re curious about the electronic dance music experience, then Monster Massive maybe be your 100-beats-per-minute ticket.” $70 for an 100-beats-per-minute ticket? Sold.

When mulling over you Saturday night options, keep Monster Massive at the top of your list: it’s Halloween as you’ve never seen it before. Gear up, stretch it out, and get ready to thrown down with the rest of the ghosts, goblins, and ghouls.
