Guitars' by Mike Oldfield was originally released in 1999.
The concept of the album was to only perform it using guitar-like instruments.
Oldfield plays all the music on the album, using only guitars of various types.
The most remarkable usage is that of his Roland MIDI-equipped guitars, which he uses to trigger drum samples and produce string-like sounds.
'Four Winds' is a four-part work, whose sections are musical portraits of the four compass points (North, South, East and West).
