There are multiple artists that share this name:

1. Ghost Mutt is a producer and DJ from Brighton. Expect sparkling synth arpeggios, chunky rhythms, chopped up divas, dirty bass and maybe a few dollops of new jack swing. He is a resident at Brighton's acclaimed Donky Pitch club night alongside Slugabed.
Check his recent interview and mix for Sonic Router: http://bit.ly/ghostm_sr

2. Ghost Mutt are a lovely little 'beach gothic' band from Airey's Inlet, Victoria. They make some sweet, sweet indie and they pull off a tight, energetic live show in their incredibly skinny jeans. They are Kasper Raglus, Jarrah Lynch and Mitch Lewis and you should like them. Read more on Last.fm.
