Lucki Eck$ is an 18-year-old rapper from Chicago who has caught the attention of some very talented people. Earlier this month we posted his “Ouch Ouch” video, which was directed by and starred FKA Twigs. “Weightin’ On,” his latest, features Danny Brown, whom he met at SXSW when they both played Red Bull’s Sound Select showcase. In contrast to the trance-like “Ouch Ouch,” this one hits hard without losing the easygoing float that has become Eck$’ trademark. There’s a trace of A$AP Rocky in Lucki’s laid-back flow, which makes for a neat contrast against Brown’s untamed yap. This one finds both rappers in their comfort zone, doing what they do and doing it well. Listen below.

“Weightin’ On” is out tomorrow, 8/12, on Red Bull Sound Select. Download Lucki Eck$’ mixtape BODY HIGH here.
