Acid Space (2015)

The famous rock band "Paperback Music" is unwittingly summoned by its drummer and manager, Phil, to take the stage for a concert at Big Depression. Phil, a drummer with an old mechanical arm, brings the band to the desolate land of Big Depression. There stands a monolith, a remnant of the first contact with an alien civilisation. Phil's arm is not the only thing that gives him problems, his brain too appears to have a few blackout of its own. He brings the band to Big Depression on the wrong day, where no concert is going to take place. Afflicted by this realisation, Phil throws his arm at the monolith, leaving his band clueless on how to keep playing music without their great drummer, now short of one arm. Suddenly the ground trembles and from a secret passage from inside the monolith comes out DoreMi, an alien in the shape of a red octopus, with great drummer skills. DoreMi will bring the band to Planio, his planet, where the tyrannical Balthazar chose to outlaw music
