HELLOWEEN recently shot a video for the re-recorded version of their former Top 10 single 'Dr. Stein', which is featured on the forthcoming Unarmed - Best Of 25th Anniversary album. It is available below.

A preview of the tracks featured on Unarmed can be heard in the YouTube clip below. The album - which is out now in Japan via JVC/Victor - will be released via Sony Music in co-op with SPV on January 29th in Europe. The release dates for North America will be announced soon.

Unarmed will also be released in a limited version with a very special digi-pack, incl. a 30 min. making-of DVD, containing interviews and studio footage... also available will be a double vinyl version.

A previous update from Helloween reads:

"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' - goose bumps guaranteed!

Here's a list of all songs we recorded:

'Dr. Stein'

'Future World'

'If I Could Fly'

'Where The Rain Grows'

'The Keeper's Trilogy'

'Eagle Fly Free'

'Perfect Gentleman'

'Forever & One'

'I Want Out'

'Falling To Pieces'

'A Tale That Wasn't Right'
