RadioHead: Street Spirit (fade out)
Not for beginners so I'll talk more upstage. I use a plectrum for this but a friend prefers the finger-per-string technique, take your pick. 
Set up with an Am chord, add 4th finger to the 3rd fret to make your sus4 and whilst playing the arpeggio pattern you use the B string to drop through sus4, minor, sus2. The dropping along the B string continues unchanged throughout the piece as you change the chord underneath it.
