Warrenh; congratulations on your finds-- that's the best part of this strange hobby, IMO! Those are two of my favorite CDs. I have all of L. McKennitt's
CDs and there are no weak ones, but as noted above, "The Visit" and "The Mask and the Mirror are excellent next choices.
Mai're Brennan (lead singer of Clannad) is another excellent Celtic/neo-Celtic singer that I really like. I have Eva Cassiday's other CDs and there is some good music there, but Blues Alley is the best. Cheers. Craig
