Gucci Mane and Zaytoven have been working together since they both scored there first hit in 2005 with "Icy," and have developed their respective sounds together ever since. Since 2013, Gucci Mane has been behind bars, unable to record music (though constantly releasing songs from his stash), while Zay has been further fine-tuning his sound, adding his signature church-informed organ sound to mixtapes from Future, Migos, and more. Gucci was released last month, and has already released one song, "First Day Out Tha Feds," a sequel to his Zaytoven collabm "First Day Out". He and Zaytoven have now officially announced that they've been recording together, sharing a clip of the two jamming on Guwop's home piano. Judging by their recent material, it's clear that together, they still have the potential to make some great music. Until that happens, we're taking a look at their past glories.
