The session musician - who has played for the likes of late music legend David Bowie, Sir Elton John, and Bob Dylan - revealed he was in the studio with the "Hello" hitmaker recently and has recorded some drum parts for the Grammy-winner's new tunes for her long-awaited follow-up to 2015's 25.
Matt admitted he got "chills" hearing Adele's "powerful and emotive" voice.
Speaking on "The Eddie Trunk" podcast on SiriusXM, he spilled, "I mean, this past week I just did, I generally do sessions with people - I'm like a session musician I guess, that's my day job - and I just got to work on some new music for Adele, and to hear that voice in my headphones was getting me chills."
"It was just so powerful and emotive. You know her voice, but to be across the room from somebody doing that, it's just insane."
"You hear it on the radio and whatever and you go, 'Yeah, it's really good,' but to be in the room with these people and feel that energy, it's just so heavy."
"She's writing some new material with her songwriter Rick Nowels, she wanted to do it with some drums and so we just put our masks on, she was in the room - yeah, holy s**t."
Eddie's update comes after it was revealed Adele recently returned to London to work on her new music.
A source claimed, "Adele wants to lay low while she's here, which is easy with shades and a face mask. People don't recognise her like they used to anyway. She's not been able to release new music yet and she's totally focused on that and getting each track just right. She still has a network of people she works with and links up with when she is over here."
