"This album is refreshingly honest - UK-based composer/guitarist Hayden plays the entire program solo and with no overdubs... flawlessly executes the genre's characteristic strums, descending single-string runs and soundboard taps... Yet he typically makes things more interesting by weaving more complex harmonies and smooth jazz elements into each of the tunes. Si Hayden's appeal comes from successfully melding flamenco with more modern sounds, and doing so without gimmicks or artifice. Both guitarists and general listeners will enjoy this CD; turn it up and enjoy."

"solo guitar mastery of U.K. based Si Hayden... The music may sound vintage but on his CD Hayden puts a new spin on a timeless art form. As he points out in his liner notes, all tracks were recorded with one guitar and no overdubs and all percussion is from the right hand on the guitar body while playing. A modern flamenco master, Hayden makes excellent use of his Ivor Maraints and Jose Ramirez guitars."
— (Robert Silverstein, 20th Century Guitar) on 'Nylon... for Now'/2006
"Hayden’s trademark supersonic picking is present.. the six-string virtuosity shown on this album is irrefutable.. an album that stuns with its technical brilliance, then later endears you to the soul and depth behind the flashiness"
— (Peter Clayton, cdreviews) on 'Steel Roots'/2007
"fast killer chops on most tracks.. "Moondance".. a true piece of art.. at times he reminds me of Tuck Andress in his jazzy approach with a lot of rhythm and bass runs going on"

"Hayden is a very acomplished guitarist, with a good range of styles and moods."

"its a ripper cd... very, very good!"
— (Steve Passiouras, PBS FM) on 'Steel Roots'/2007
"It's really nice to hear new music with real musicians, I do a lot of programmed music, but there is something organic about poetry and well tuned musicians. And Si's work is just great, the double bass playing is spot on... it really sounds like the musicians overstood the poetry. Nice one." (Album-Backra Men)

"A classical Spanish style guitarist, who will blow you away with his jazz, latin and funk infused songs. How he manages it all on just a 6 string guitar still amazes us. You will have to see him to believe it!"
— (AcousticLounge, Clapham)
"Coventrys Si Hayden simply blew us away with his intricate finger skills"
