Kim Thayil channeled the loss of Chris Cornell in his solo on the new Mastodon album

Mastodon’s new album, Hushed and Grim, is a staggering achievement: every second of its 86:30 runtime is crammed with arena-shaking riffs, haunting clean passages and sky-scraping solos, courtesy of ever-bankable guitarists Bill Kelliher and Brent Hinds – but there are a few special guests onboard, too, including Kim Thayil, who lends his unmistakable leads to ethereal ballad Had It All.

Now, in a new interview with Total Guitar, Kelliher has detailed Thayil’s involvement in the track, and how the Soundgarden guitarist dialed his playing into its themes of loss, which deal with the death of longtime Mastodon manager Nick John.

“I’ve always looked up to Kim,” Kelliher says. “He started coming to our gigs in Seattle and we became friends.

“I knew there would be a lot of room for him to solo on Had It All. He wanted to get it right and asked, ‘Do you need something like this or that?’ I wanted to send him the whole album so he could get a feel for the sadness and emotion.

“I said to him, ‘You guys lost Chris [Cornell], just channel that!’ because that’s what the song is about. Losing our manager, someone who we were very close to. Kim did a great job – his solos are out there and nobody plays like him.”

In the years following Chris Cornell’s passing in May 2017, Thayil has toured with MC5 supergroup MC50, performed Soundgarden material with Brandi Carlile, and served up a sizeable lead on The Pretty Reckless single Only Love Can Save Me Now. Had It All marks his latest guest solo spot.

Elsewhere in the Total Guitar interview, Kelliher reveals how the record’s other guest soloist, Marcus King, ended up tackling The Beast.

“Brent’s been playing with Marcus a lot on the side, doing shows and covers,” he explains.

“He’s a young up-and-coming blues guitarist and to my ears, they sound very similar. Marcus did a stab at a couple of solos on the record and I couldn’t really tell who was playing!”
