The Bay Area rapper and producer Young L was the driving force behind the Pack, the mid-’00s Berkeley group that also gave us Lil B. It was L’s icy, strange, minimal beats that powered tracks like “Vans.” Young L has been solo for nearly a decade now, and he’s kept up his record of making mesmerizing, oblique rap beats. (I gave him Mixtape Of The Week a couple of times when I was still doing that column.) Today, he’s come out with a brief but sharp and inventive new tape called The Boo Ghost, and you can hear it below.

The self-released The Boo Ghost is out now at iTunes.
