Tony McManus is well known around the world as the most accomplished practitioner of fingerstyle Celtic guitar playing, but when friend and mandolinist Mike Marshall challenged him to learn Bach's E major Prelude for solo violin on the guitar, he was forced to look at his instrument in a new light and think in a completely different style. McManus not only took Marshall up on his challenge, but also proceeded to learn more classical guitar pieces, creating a unique collection of performances that he has collected on this new album. 'Mysterious Boundaries' demonstrates just how much of a virtuoso McManus really is and simultaneously raises the bar in the world of fingerstyle guitar.
