It is amazing. I did the guitar and bass and the drums are programmed. To me, that's the hardest part, making the drums sound real. It takes a lot of time to do that.

The guitars are layered and slightly detuned a fraction higher and a fraction lower than the actual take, then blended in the mix together to make it sound thick.

The keyboard was played on this tiny little keyboard with mostly one finger and connected to a computer with sampled keys sounds in it.
