Prepare to either be amazed or terrified by the incredible and haunting music from the first "underwater band".

The band, called AquaSonic is the brainchild of singer and composer Laila Skovmand, who has spent 10 years experimenting with techniques and technologies. Their first concert will take place on May 27, at a festival in Rotterdam.

As reported by New Scientist, Skovmand has trained herself in producing an underwater steady vibrato, keeping an air bubble constantly in her mouth, a technique she herself has developed. She tested traditional instruments underwater and she eventually partnered with Andy Cavatorta, an expert in constructing unusual instruments.

He invented two new instruments: the rotacorda, a sort of underwater guitar that uses a mechanical hammer to pluck the strings, and the crystallophone, a modified version of Franklin’s glass harmonica that sounds like a violin.

You can check out a video of their somewhat odd music below.
