My complaint about most DC rock bands is that they take themselves and their music far too seriously. The ladies of DC’s newest sensation Ex Hex are a breath of fresh air. Laura Harris, Betsy Wright and Mary Timony, veterans of many notable DC bands, are clearly having a blast rocking out together and their enthusiasm is infectious. “Waterfall”, the b-side from their debut 7″, gets the music video makeover from underground cartoonist M. Wartella, and it’s instantly one of my favorites of the year. The band flies around in a funky UFO zapping coolness into the likes of Kid Congo Powers, The Make-Up’s Michelle Mae, Alec MacKaye and Francy Graham from Chain & The Gang. If you’re still wondering what costume to wear on Halloween this year, take some notes from this video.
