Well Oasis released their latest album last autumn, which the OP tune is already included, so any Oasis fans can go hop off for those, or you can grab the single from Japan if it's just the OP that's catching ya.
As for the ED...

For a series that's only 11 eps, that's gonna get released around ep 8, so kinda late in my opinion :\
But it's their first official single, so I guess they're just about beginning to debut (although they've been doing small live performances for a while) but this isn't a bad beginning to their career.
Ha... ironically the OST gets released around the same time...
