This is my personal adaptation, makes it sound a bit better, simple riff, if it's too hard for someone, just play on the B and D string or A and E string. Make sure your guitar is tuned well for this to sound properly. Repeat this riff all the time, pretty simple. Later on the effects and percussions come in. * = optional sound E|=|-----------------------------------------------------| B|=|--1/3----4/3----6---4/3--1-1/3-----------------------| G|=|--------------------------------0*---------------0*--| D|=|--------------------------------5----3----7----8-5---| A|=|--3/5----6/5----8---6/5--3-3/5-----------------------| E|=|--------------------------------3----1----5----6-3---| Band site: http://www.myspace.com/interstellartheband
