Behemoth will be rejoined by former members Adam “Baal Ravenlock” Muraszko and Leszek “Les” Dziegielewski during their 'Merry Christless‘ shows at Progresja in Warsaw, Poland on December 14-15. The band said the following:
"If you thought you will never see „Grom” line up one stage one day... you’ve been wrong! Former drummer Baal and Les will reunite with Nergal for BOTH Merry Christless shows in Poland, Warsaw on 14th and 15th December. And it’s not all the surprices to come during these special events...!🤘There's very few tickets left for 14th so hurry up before it's sold out!"
