Four stars and not five because Stivell's second album - "Renaissance" - is THE celtic harp album and the five star choice.
However, this one is a hidden treasure with some good songs on it - a mix of Breton, English and Irish. Stivell's harp playing is unique and more expressive than classically trained harp players, which most "celtic harpers" are; Stivell is more fluid and freely borrows from finger-picking guitar technique which translates very well on to his metal-strung harp.
I first heard this album (then a 12" vinyl) in 1977 when I was a heavy metal fan, by chance handed to me by a French girlfriend. I then got "Renaissance" and played the two incessantly for two years, gave up completely on the heavy metal and bought a celtic harp and learnt how to play it. Stivell was that influential for me.
If you like celtic music, buy this one and "Renaissance" - they are a must for the CD shelf.
