Inspired by the other thread, I want to know which artists have you GAINED interest in, maybe because of a smash surprise album?

Or just because you discovered their music and you eventually became a fan, talk about it here. I became a Lady Gaga fan in 2012 having been a hater before, and I also started to love Katy Perry a lot recently because the Teenage Dream era was almost eternal, so it was extremely exciting to finally see a different album, different colors, different direction and everything.
