The hype for ASAP Rocky's second album continues to grow, but Flacko's been less forthcoming than most artists when it comes to details. We don't know any of ALLA's rap features, though we know it will feature R&B genre bender FKA Twigs and Swedish pop singer Lykke Li. We also know one of Rocky's main producers, Clams Casino, will be back--and, for now, that's enough to keep us going.

Without Clams Casino, there might not be an ASAP Rocky. Or, at least, his come-up wouldn't have happened nearly as fast as it did. Of course, it goes vice versa, too. After working with Rocky, Clammy Clams has gone on to produce for Mac Miller, Schoolboy Q, Jhené Aiko, and the aforementioned FKA Twigs. Clams produced five tracks on Live.Love.A$AP, the coming-out tape that brought Rocky instant celebrity. Though it's pretty hard to fuck up a Casino beat, A$AP Clams' chemistry goes unmatched. They brought the world a brand of hip-hop that's emotional, druggy, and chalked full of swag; clique anthems that are simultaneously turned up and down. A strange, indescribable mix that still needs to be explored. On Rocky's debut album, we only got two Clammy beats. Let's hope to get that number back up this time around.
