Sure, there are massive parties and club nights where you can celebrate Halloween this weekend — but you'll probably have more fun at an intimate gathering like Easy Killer: It's a Halloween Party. Filled with local favorites — Roy England (pictured; Make Mistakes), Ejay (Hotbox, Spellbound Music), Khalib (Treehouse Collective, Spellbound Music) and Ivy (Black Feather Files, Communikey) — and held in the electronica-friendly Apex Movement parkour gym in Boulder, this is an affordable alternative to the higher price tags you'll see elsewhere. Catch England and the rest of the crew on Saturday, October 29, starting at 11 p.m., for just $15. This is a lineup that'll be sure to keep you dancing till the lights come up.
