What does hip-hop have in common with the study of physics? Well, both are heavily concerned with bodies in motion—and, on a more relevant note, they both take serious smarts to do right. On the Washingtonian emcee’s first Booth feature, Sol gets his Albert Einstein on, reflecting upon the cerebral side of his craft over a moody piano beat by Jacks Green and Pseudonym. Sol’s next album, Yours Truly, has yet to receive a drop date, but Boothgoers will be the first to kjnow when that changes. In the meantime, fans can click here to peep some live footage of the artist performing Albert Einstein.
