Enid is a, well I guess you'd have to call them an Americana band. But starting off, as I did, with "Have Yourself A Merry Little Christmas", my immediate thought was Chamber Pop. And, for the most part, having heard the rest, I'm still comfortable with a Chamber Pop designation. The rest of the set is certainly more "rural" sounding, which, itself, is odd since the band hails from New York, New York. There's not anything more I can tell you since the band doesn't have a bio at their web site and they don't have a Facebook page. I can certainly tell you that this Enid is not the progressive rock band Enid from the UK (kids, what have I always told you about googling your proposed band name before you take it on?).
The vocals are very pretty throughout the EP. I liked those. And there's an easy intimacy about the group, as though they were serenading you from the breakfast nook (assuming you had a breakfast nook). My fave tracks are "Have Yourself A Merry Little Christmas", "There's A Light" and, yes, I gave them the "O Holy Night" test and they passed (not that its a top ten version of the song, but its very nice). You'll find "A Very Enid Christmas" and individual tracks up on Soundcloud--free to download (though it may be a one track at a time thing).
