In this song, Bob Saganas uses an 8-string guitar on which he masterfully reproduces his mind-blowing phrases and melismas. The musical composition 'Grey Matter' consists of several stages, each of which is connected by solo moments of playing the guitar.  

Flamenco riffs and rock solos filled with flageolets and tapping sound rich, expressive and melodious. The elements of math rock and prog metal perfectly intersect here with the classic harmonies of the baroque era and folk vibes.  

Bob Saganas is a talented and promising guitarist and we highly recommend listening to his single 'Grey Matter' right now on Spotify below.
