[2] Almqvist is known for being particularly animated during live shows, and his onstage antics have earned the band the title of "The best live band in the world" from Spin Magazine, who also put Almqvist in their list of the "50 Greatest Frontmen of All Time".

Some of his onstage antics include regularly mixing with the crowd, climbing on amps and other equipment, and banter between songs that is often nonsensical and seemingly arrogant.

Almqvist was previously in a relationship with Maria Andersson, lead vocalist of the Swedish rock band Sahara Hotnights, until a 2006 breakup.

[4] Almqvist collaborated with Swedish rock artist Moneybrother on a cover of the Operation Ivy song "Freeze Up".

They used Swedish lyrics and called it "Jag skriver inte på nåt", which translates as "I Won't Sign Anything".
