From Substantial’s fifth solo album, “Adultish”, 1580 is a tribute to the late, shortlived Rap and Go-Go station, Flava 1580AM, and to the ups and downs of growing in Prince George’s County in the 90s. Substantial teams back up with his friends, DMV Hip-Hop staples DJ RBI and T. Lucas over chill boom-bap production highlighting the nostalgic lyrics and razor-sharp cuts.
