Just in time for Halloween, Chief Keef and Gucci Mane release a ghoulish new mixtape called 'Big Gucci Sosa.'

The 12-track collection features everything you can expect from Sosa and LaFlare. All of the songs boast thunderous traps beats, eerie synths and repetitive choruses. Both Keef and Mane rap about collecting money, bagging women and giving foes their comeuppance.

On 'Banger,' Mane gives a stern warning to anyone who doesn't come with the right count with his money. On 'Paper,' Chief raps stacking chips on the daily.

"I'm a 'Lunatic, I don't do Nelly / Hey, I'm rowland [rollin'] and I don't know Kelly / Racks up in my jeans and I don't have no belly / Walked up in Saks, throwin' up racks, they smell me," he raps.

In addition to 'Big Gucci Sosa,' Chief Keef dropped another mixtape called 'Back From the Dead 2.' The collection features solo tracks from the Chicago rapper, which he produced as well.

If you are fan of both Chief Keef and Gucci Mane, here are two treats that are perfect for your Halloween day enjoyment.
