Instrumental artists to recommend?

When I write, whether it's poetry or articles, I like to surround my soundscape with instrumental tunes. Music without lyrics is ideal for my writing sessions, because lyrics can often cloud my head with vocabulary that distracts me from the words I want to get down on paper.

So this blog post is a little request: Which instrumental-friendly artists do you like listening to? I prefer more chill tunes, than high-energy EDM, in the style of Ratatat, RJD2, J Dilla.

I'm a fan of many music genres, such as electronica, hip-hop, jazz, funk, etc. 

So suggest away in the Comments section below! Or if you're following me on Twitter, feel free to pepper me with your recommendations.
