This is a terrific album. Some compilation albums can be uneven, this is consistently good. Loreena McKennitt's Anachie Gordon is very good, from one of her earlier albums. I especially like the 4th track, Tonight Is Just For Us. This is a CD I'll listen to a lot.
I also like the fact that they published the lyrics in the liner notes.
With the explosion of celtic music, there is a lot available - good, bad, and mediocre, and of course a lot of it depends on personal taste. To gauge similar tastes, I also like Loreena McKennitt, Clannad/Maire Brennan, Sinead O'Connor, the Putamayo Celtic Women of the World 1 (but not 2), and the Women of Heart series.
