Gray died of a suspected overdose in June last year and there were suggestions at the time that the Iowa metallers would not continue without him. Ultimately though, they have decided to tour this summer, with temporary bassist Donnie Steele performing in Gray‘s stead.
The band, who headline Sonisphere Festival on July 10, will host a two-minute silence at 2pm (BST). The band have chosen 2pm as Gray wore number two on his version of the band’s signature boilersuits.
Fans will also be able to leave their written dedications to Gray in a book of remembrance, which will be left in the festival’s signing tent for the course of the weekend. It will then by given to Slipknot at the end of the festival.
Slipknot headline the final night of Sonisphere Festival, which takes place at Knebworth Park on July 8–10. Metallica, Biffy Clyro, Weezer and Slayer are among the other bands playing across the weekend.
