Alchemist and G Rap reunite for “Diesel”.

Hot off his Continuance album with Curren$y, The Alchemist cranks up the juice on his new single featuring Kool G Rap.

Fueled by Al’s brolic beat, the Queens veteran delivers an abundance of brawny bars full of grit.

The two recently collaborated on 2013’s “Problems” and 2012’s “Vodka & Ayahuasca“.
