Studio footage from The Great Escape recording sessions were posted on the band's official forum and YouTube channel.

Following the release of the band's sixth studio album, The Testament,[5] Karevik announced his departure from Seventh Wonder on 12 June 2023.

Kamelot was forced to tour without their longtime vocalist Roy Khan, who was unable to perform due to personal problems and health issues.

During Kamelot's tour of Europe, Karevik joined the crew, singing mostly backing vocals, but also performing solo on the songs EdenEcho and Center of the Universe.

On August 31, 2013, Karevik was announced as a guest vocalist, playing the lead role, in the progressive rock opera project Ayreon's album The Theory of Everything.

In an interview with vocal coach, Elizabeth Zharoff of The Charismatic Voice, he told that, before discovering metal, he listened mostly to pop music as a teenager.

Karevik also added that great vocalists like Mariah Carey and Whitney Houston, had surely influenced his vocal style.

Karevik cited singers Jørn Lande, Russell Allen, James LaBrie and the bands Queen and Dream Theater as some of his main influences.
