LIBRAVEL (リブラヴェル) has released a new maxi-single.
Hoshi ni NEgai wo。 (星にネがいを。) was released on September 3rd, exclusive to iTunes.
(although, at the time of writing this it looks like it isn't actually available?). Their Twitter states that the album will be out "during September," so stay tuned.
For reference: LIBRAVEL is the band of an ex-AVANCHICK (アヴァンチック) guitarist, and seems to be very similarly themed.
If you are interested in purchasing it yourself, here is a link to the album.
