[Insert Band Name Here]?
Who are they?
Where did they come from?
Why are they here?
Let's see.
Not even DJ Stitched Mouth, president of their record label, has met them in person.
But we will tell you what we do know...

The band consists of two members, who's names are unknown.
Their band name changes for every studio album recorded.
Rumor has it that these two may never do a live show for us.
But if they do, no one will ever see them.
Their first album is going to be all cover songs.
Mostly consisting of instrumental cover songs.
