A detailed description of the CDs and a link to the group is below the cut.
They've released 2 studio albums as of this date, and I first bought Vol. 2, which is subtitled as 이상한 계절(Strange Season). I went for the second first, because I was introduced to the song 'Electric' by a K-drama blog titled 'Electric Ground'. The following video was uploaded by the aforementioned website.
Vol 1, non-linear, was not available from YesAsia.com which I bought Vol 2 from a few weeks ago. All the usual korean websites told me that this was not coming back into print. But somehow, Amazon had a copy. I like this duo a lot, and hope their collaboration isn't over. I hope I can discover more about their individual works as well.
Wikipedia has no information about them, but I found a nice little article among the myriad of reviews when I googled them: A Meeting with MOT (fr. London Korean Links).
The layout of both albums is similar. They are tri-folded, with a paper case. They come with a booklet of lyrics and illustrations, sketches, collages, photographs, and thank yous.
