Both excellent picks. I think @luzcypher is another excellent suggestion as that account is actively pouring through the #openmic submissions and providing a highly relevant curation trail (as @meno pointed out in his latest post.) The @dsound account is also extremely actively curating content with a combination of bot driven combing and human review. They are killing it.

Musician-wise there are tons emerging every day, but special shoutouts to steemit producers @harrisonmir, @granturismo89, @juliakponsford, and @heymattsokol for putting legwork helping people new to the community in addition to being great artists themselves, which is pretty much essence of being awesome at Steemit IMHO.
