She dropped two EPs this year:

Favorite track: "Smoke & Mirrors"

The Beauty of Everything, Pt. 2 (May 2019)
Favorite track: Tie between "Love On-Demand"

and "We'll Always Have Paris"

"Love On-Demand" features SiR but his name isn't listed in the title. That was a pleasant surprise because I love that man's voice. He's one of my favorite new male vocalists, and I enjoy his work with Chris Dave.

I discovered Alex via a webseries Issa Rae published on her YouTube channel. I think it was called "First." The song was "Child's Play," which sounds like it features Paris Strother of KING on background. The two have collaborated before on "So Here It Goes"

Her father is Ernie Isley, and I think she sang backup for Robin Thicke.

I think some of her songs sound too similiar, but she's definitely someone to look out for. While searching on YouTube, I saw she made an entry into NPR's "Tiny Desk" series. I hope they pick her. Good exposure.
