This weekend, we got you covered on laughs, anniversary parties and formal dances to make it one of those classic crazy April weekends. Check out even more to do on the Westword calendar, and don't hesitate to drop a comment id if we missed anything.

One Year Anniversary Party at Block 1750 (8 p.m. Friday, free)
Block 1750 has been holding it down in Boulder as a place for the kids to go and dance. Five days a week they offer classes for kids and ways for those in the community to learn the values of love and peace through the medium of dance. They've made it a year and hopefully many more years to come. Stop by the spot tonight to congratulate them, learn about the space and of course dance.

Adam Cayton-Holland Backyards Album Release Party at Hi-dive (8:30 p.m. Friday, $10)
Denver's golden boy of comedy celebrates his latest offering of hilarity tonight at the hi-dive and he's bringing his friends, because it ain't no fun if the homies can't have none. Kevin O'Brien, Troy Walker, Ned Garthe Explosion and Total Ghost join the release party for Backyards, for what can almost be classified as an overload of jokes and tunes for one night. And for $10 do you not only get in the door, but receive a copy of the album to take home and giggle in the dark to.

Spring Sugar Plum Bazaar at McNichols Building (10 a.m. Saturday-Sunday, free)
Mother's Day will be here before you know it. It's also wedding and graduation season, so pop on into this bazaar this and pick up a few trinkets from local artisans who work hard on their crafts. You know there's always good food to try at these sorts of things — and music too. The Colorado Ballet will do some performances, so donate $5 to them if you can. 

Feminism & Co. Wikipedia Edit-A-Thon at Museum of Contemporary Art Denver (12 p.m. Saturday, $10)
Even though much of what is on Wikipedia is true, there is also a lot of false information out as well — and using the online encyclopeida at the academic level is frowned upon. As part of the MCA's Feminism & Co. lecture series, spend the day fact checking and updating wiki-pages on feminine art and culture. Support your sisters and b.y.o. laptop if possible.

One Year Anniversary Party at DADA Art Bar (4 p.m. Saturday, free)
DADA had a rough start trying to open it's doors, but once the red tape got sorted out, they've been a breath of fresh air to the Denver bar/art scene. Show the place some love and help them celebrate turning a year old with drinks, live music and some barbecue. They only turn one, once — so bring yourself.

Rockabilly On Broadway Artists Gathering #4 at Mutiny Information Cafe (7 p.m. Saturday, free)
Once all you hepcats are done playing some back seat bingo, cruise over to the Mutiny for an all out rockabilly free for all. Sounds coming at you from The Colfax Cannonballs / Brian Parton, Surf-Squid and The Wind Up Boys and True Kustom Paint and Fabrication show off their motorcycles and do pinstriping demo's. Get ready for the go-go dancers and and live artists as well. It's going to tune you out, man.

Vegan Prom Denver at Mercury Cafe (8 p.m. Saturday, $10)
Get your $10 tickets here, Nooch or at Watercourse Foods because the price goes up a little at the door for this cruelty-free formal. These throwback parties are great for the ones you blew in high school, especially this one which supports the Peaceful Prairie Sanctuary from your ticket cost. Enjoy vegan snacks galore, music from The Gin Doctors and DJ Brian Polk and too many door prizes to list. Hopefully you don't live with mom anymore, because this party is going to go way past curfew.

Gadgets & Gizmos Steampunk Dance Party at Tracks (9 p.m. Friday, free-$10)
Get creative with it because there's a best dressed contest happening, for prizes of course. Not only is the steampunk gear going to be nuts, they're also having a LARP weapons contest. Assemble the craziest mace/ginza sword/ shield, or something to win, assuming it's made out of foam or something not too lethal. If you're fashionably late, you'll pay the price, because it costs $10 after 10 p.m.  

Where's My Hoverboard?! Film Fundraiser for Buntport Theater at Alamo Drafthouse (12 p.m. Sunday, $10)
Back to the Future II is the wildcard of the series. The film makers nailed the 1950s and the 1880's but their rendition of the future in part two was a lie. Cars ain't flying, clothes are not drying and let's not even get started on the hoverboard. Nonetheless, it's still a lot of fun, especially on the big screen. Get down to Littleton for this special screening which also benefits the Buntport Theater, who always provide this town with quality entertainment. Don't forget to dress up for the costume contest and future of now discussion.  

The Church of Coen Presents: Barton Fink at Syntax Physic Opera (10 p.m. Sunday, free)
The Coen Brothers really became what they would become in Barton Fink. The fourth offering by the holy directors is a true religious experience layered with metaphors of faith and noir. It also features one of the best endings in all of cinema history. Wrap the weekend up tightly and partake in the experience that is the Church of Coen. Enjoy a musical selection by Andy Thomas' Dust Heart and discussion to follow.
