I haven't really been looking, but...since their so new, if there isn't a live dvd there probably aren't any vids yet.
The PV will probably be out in about a month since the single comes out in September.
EDIT: I found some pictures...but that's it. I found them here:
Lc5 live pictures - Orble
I just found out that Teruki has been playing support for the band Dog in the PWO...I wish to see this.
