Wergeland, of Octavia Sperati fame, joined The Gathering following van Giersbergen’s exit in 2007 and contributed to three studio albums and several tours during her tenure.
Notably, The Gathering have recently been performing with van Giersbergen as part of their Mandylion 30th-anniversary celebrations, with additional tour dates planned for 2026.
A statement from the band reads as follows: "We'd like to thank Silje for her contribution to the band over the past 16 years. We're very proud of the wonderful records we've made together (from The West Pole to Beautiful Distortion), and all the shows we've played. We will miss her as a fantastic vocalist and a dear friend. We wish her all the best in the future!"
In turn, Silje Wergeland commented: "It's a new dawn and a new year. After 16 years of creating and playing great music with The Gathering, it's time to move on to new ventures. I have had so many awesome experiences and made great memories with this band that will stay with me for the rest of my life. I wish my band mates all the best for the future. Thanks for all the great support and the lovely conversations with all you wonderful TG fans around the globe."
