The good people at Metal Recusants recently conducted an interview with Amon Amarth bassist Ted Lundström (which you can find below). In the process, he unveiled that the band is in fact working on a brand new album. More specifically, he had the following to say:
"We just started very recently. We have some ideas for songs and lyrics, but we haven't really sat down to put it together yet. But after this tour, that will be our main focus, just to work on the album 24/7. So hopefully we can record it after the summer. That's the plan. But we don't have any finished songs yet.
…I would hope that we can release it early next year. But it depends on so many factors: record label and release schedule and touring and studio time and all that. But hopefully early next year… that would be our plan."
