The Internet's founding members Syd and Matt Martians have each released excellent solo albums this winter and now it's their youngest bandmate's turn: Steve Lacy.

Playing with the band throughout high school, the 18-year-old guitarist and producer is credited by many for shaping the groovy sound found on the group's breakout album Ego Death. Finally graduated from school, he's toured with The Internet, produced a song for Big Sean and Jhené Aiko's TWENTY88 project, and featured on Kali Uchis' "Only Girl."

Last month, Martians admitted that his own album wouldn't have been possible without Lacy and told me over the phone, "Steve is like the first little brother I've had, for real. But then again, he's like an older brother, too, because he teaches me things. He's ten years younger than me, so he teaches me things about new ways of thinking and new ideas."

Now, after a couple years of sharing addicting loosies on his SoundCloud page (including my personal favorite "thats no fun") Lacy's first body of work as a solo artist has arrived in the form of Steve Lacy's Demo—made entirely on his iPhone in GarageBand. Dive in via Apple Music below. Lacy clarified that it should be available on all streaming services by Friday morning.
