TWO-MIX released a bonus issue of their fanclub newsletter right before
the release of "DELTA ONE" last week, and some fanclub members wrote
about it in their blogs. Here's what I've managed to gather about this
whole "II MIX DELTA" business from these blog entries:

-TWO-MIX the band is to be considered officially on hiatus while the
members are producing music as II MIX DELTA

- the band had originally hoped to release some songs credited as
TWO-MIX in collaboration with Joe Rinoie, but this didn't work out due
to schedule conflicts and Takayama's recent marriage; the three decided
to form II MIX DELTA instead for the time being

-II MIX DELTA is to be considered as a group of three individual
musicians, not "TWO-MIX + Joe Rinoie"; as a result, the two members of
TWO-MIX are currently under the management of yet another different
group, and news may potentially be slow coming on both the Little
Station and MTM (TWO-MIX's fanclub) websites

-the trio currently plans to produce music together for about 2 years,
hopefully releasing some songs/CD every 3~4 months

-on the topic of the new mini-album "DELTA ONE", apparently the fifth
track "Etranger" was written in reference to the song "THOUSAND NIGHTS"
and to mark TWO-MIX's 10th anniversary

Speaking of "DELTA ONE", for those of you who haven't managed to pick
it up yet, here's an updated list of places online where the new
mini-album is now available:
