I'm going to do a form of self pimping here. Although, to be honest, because I run a record label, I just get to put out music by favourite artists, so it's sincere ALSO:
DJ Deathray, sort of electro-flavoured witch... bit of a weird one, but definitely a grower of an album

Aparition, again, almost post-witch, but very, very good
http://auralsects.bandcamp.com/album/to ... nihilation
Moon Mirror, mix of 80s synth film soundtracks, modern sensibilities, pop and goth:
http://auralsects.bandcamp.com/album/transgalactic
MARIE DIOR: basically if lo-fi dance music and witch house had a hideous baby
http://auralsects.bandcamp.com/album/7
Tash Willmore: poppy witch house. I fucking love Tash, and I can see he's been recommended above:

Peach Black... these kids are gonna be big if they play their cards right:

And ▲AIMON. Really. Don't sleep on those guys, they're nothing short of "Pure" genius.
