As their name would make you believe, Sleigher slays, and they do so as a totally improvised, two person unit. Self-recording the music at their house with a guitar, drums, and piano, the results are surprisingly good. This isn't God-awful "Who Line Is It Anyway" improv that leaves you without the ability to laugh for a few hours, this is "Holy Shit, This Is Actually Improv" improv. Sleigher's music ranges from melodic indie rock to technical metal, with transitions usually occurring with the drummer and the tapping of his cymbals. The music can go from lo-fi indie rock, and then tap-tap-tap, and everything speeds up and machine-gum drumming and break-neck guitar playing takes it's place. A few minutes later, the music is thick and sludgy, and then it's back to slow indie pop music. There are some parts that make it obvious that this is totally improvised, but it truly is a wonder to listen and hear two people making music based on what the other person is playing with no practice at all. Plus, you have to respect a label that says, "Hey go play and record something at random, I'll put it out for you."
