If you're looking for more mashups, check out Girl Talk, Milkman, and Super Mash Bros.

If you like Knife Party, you might like the band's main project (Knife Party is a mini-project by two band members from a group named Pendulum.) They do fantastic drum and bass. Immersion, their most recent album, may be their best.

The Island Pt. II: http://www.youtube.com/watch?v=CBIYl88Zwyc Witchcraft: http://www.youtube.com/watch?v=AooMCiV2eb4

Their other albums, In Silico (Showdown, the Temptest) and Hold Your Colour (Slam, Blood Sugar) are also fantastic. My favorite band, personally.

That explains why I like both Knife Party and Pendulum's sound. Set Me On Fire is an awesome Pendulum track.

Big +1 to Girl Talk. When I listen to Feed The Animals or All Day, I feel like there's nothing I can't achieve. Still hasn't failed me.

Milkman and Super Mash Bros is good too but I just don't get the same feel.

Porter Robinson's new single, Language, is phenomenal. Thanks for these links!

I've never understood how anyone can do anything productive while listening to these. They're just loud, repetitive noise to me.

That Porter Robinson set is awesome. Thanks for this list.
