As I’ve gotten older, I find I spend less time searching out new music than I did in my teens and 20s. I guess that’s natural, as other things take up space during the day. Frankly, I get a lot of my introductions to “new” artists and music on forums like this, just by clicking on links (and sometimes spending a few hours clicking on other links at those links and so on and so on…).
A lot of the “new” music I find is actually “old” music I just haven’t heard. As far as artists debuting in the 2010s and currently in heavy rotation for me, I can think of a few:
First Aid Kit (technically, their first EP was a couple of years before 2010, but they really hit the scene after 2010)
Lauren Ruth Ward (A genuine post 2010 artist. I read an interview in LA Weekly, back when it was a readable publication, and found her videos on YouTube)
Jinjer (The current lineup is definitely post 2010. Just discovered this band a couple of weeks ago in a thread in this forum and spent a few hours over the past few weeks listening to various live and studio performances.)
