2009's Unarmed is the 25th Anniversary celebration album by German power metal band Helloween which features re-recorded versions of songs from the band's back catalog in an acoustic/symphonic style. Produced by longtime collaborator Charlie Bauerfeind, the 70-piece Prague Symphony Orchestra performs on the 17-minute medley "The Keeper's Trilogy" while additional guests appear throughout.
The band explained, "'Unarmed - Best Of 25th Anniversary' is a big 'thank-you' to all our fans, old and new, all over the world! Instead of putting together a regular greatest-hits compilation featuring our most successful tracks to celebrate this anniversary, we completely rearranged and re-recorded the greatest songs and melodies of our career. Together with our tried and tested producer, Charlie Bauerfeind, we invited many great musicians to guest on this special record, with the doubtless highlight of having the 70-piece Prague Symphonic Orchestra performing 'The Keeper's Trilogy', a 17-minute medley consisting of the songs 'Halloween', 'Keeper Of The Seven Keys' and 'The King for A 1000 Years'...It was a big challenge and great experience and we had a lot of fun recording our most important tracks in an entirely new 'outfit' and with new arrangements."
This 2020 Remaster is presented as a colored vinyl 2LP-set with a gatefold cover and padded inner sleeves.
