Back-On is a JRock group known for different anime (Air Gear's opening: Chain) and live action show songs (Ending theme of Keitai Sousakan 7).
Members include: KENJI03, TEEDA, SHU, GORI, ICCHAN
The original name for the group, which started in 2000, was "Garden" but it was changed to 爆音 which is the sound of explosion. Mix it into english and you get "Back-On" (due to sound).
My favorite song is "Sands of Time" which is the ending theme to Keitai Sousakan 7.
Music will most likely NOT be in a local store, but if you pay a visit to cdjapan.co.jp you'll most likely find them. (That link goes to a direct search for the group, to make it easier.)
So are there any other fans of this band? DISCUSS!
