Congratulations to .mute on winning the remix competition for Christopher Willits album, Tiger Flower Circle Sun! You can hear .mute's winning entry, along with a whopping 50 of Christopher's favorite remixes, at Overlap.org. The compilation is available as a download for your preferred price - including free, if you'd like.
There are a number of plug-ins available for making glitchy stutters - including Ableton Live's Beat Repeat. If you don't feel like going the Beat Repeat route, you can get your hands dirty in Live's Arrangement View and make your own stutters by chopping and rearranging audio. MacProVideo's G.W. Childs IV demonstrates this method in a new tutorial.
