BE:FIRST's Mainstream CD + Blu-ray. CD Tracklist: 1. Mainstream 2. SOS 3. Grow up The Blu-ray includes live footage from the D.U.N.K Showcase. I think it's worth watching just for that. I had multiple copies, so I'm selling one. I haven't used it much, but it has been stored at home, so please understand before purchasing. I plan to ship it in bubble wrap and an OPP bag to prevent water damage. Thank you.
