BiS and... Dorothy Little Happy? GET YOU PV.

If you enjoyed this bizarre clash of worlds - - and the song is quite gorgeous and a big grower - - you're in luck: The maxi single is released on the 9th of January, and in addition to this song features BiS covering DLH's "Demo Sayonara" and DLH covering BiS' "nerve".  AND, get this, they'll hold a two-man live on the 14th of January. Exactly how the DLH fanbase reacts to that I don't know.
