Gramatik has just released his 2nd single off of his upcoming album ‘The Age of Reason.' The track is called “You Don't Understand” which features the guitarist Don Daro. Gramatik said “I recommend a Cuban Cigar & an Old-Fashioned while listening to this.” Here Gramatik goes back to his electro soul/jazz roots, so this is one you don't want to miss out on.
