An experimentalist in the context of music is someone that strives to create new forms through hitherto unheard of methods.

DJ Spooky, father of the illbient movement in New York City is an experimentalist because he combines, or in his words recombines two different styles, like hip-hop and ambient. Lustmord is an experimentalist in the dark ambient sense. His methods include using scientific archive samples like the sound of fusion occuring and deep water recordings.
