The basic comes from playing a Cmaj7/G chord in the key of G and basically moving that shape up through the scale.
Works great for an Indie vibe in the open keys of G/Em and C/Am. Also works equally well in all keys as thick drivy chords not using open strings.
Works great in combination with Power Chords, Shell Chords, Drop 2 Voicings, and Inverted Power Chords
Easy to use with basic progressions but can be hard depending on the speed and changes.
