EXCLUSIVE

Kanye West and Drake working together on a song for Ye's new album is a big deal ... but it seems like the 2 hip-hop icons are teaming up in Wyoming for a whole lot more.

Sources in Jackson Hole tell TMZ ... both rappers are staying at the Amangani luxury hotel and resort under an alias, and have each brought a huge crew with them. We already knew about Kanye's, but we're told Drake's team includes his engineer, songwriter, and as we reported ... his personal photog/videographer.

We've learned even more big names are there than we originally thought too -- like Lil Uzi Vert -- along with a slew of major producers who work with Kanye and Drake.

There's more -- our sources say the guys brought a ton of audio and recording equipment with them, most likely to set up their own studio at Kanye's crib ... because he's staying at a separate house at the resort away from the main hotel.

We're told famed personal chef Paul Zlatos -- who used to work for Oprah -- is also on hand for the group to keep them well fed.
