Andrew and Sarah from the Barr Brothers are also involved in this very interesting group: Esmerine.

Found these guys thanks to the recent post from Lucas in the Video thread. Is that really "Happy Snails"? There's an adapted version on their record with a different title, Trampolin.
Anyway, enjoy!
