Live at the O2 Arena + Rarities is the third live album by the rock band Alter Bridge. The CD was recorded at the band's show to at London's O2 Arena on November 24, 2016. The live album comes only 11 months after the release of their 2016 studio album The Last Hero. Live at the O2 Arena + Rarities is scheduled to be a 3-disc release with the first 2 discs being the live concert from London and the third disc being comprised of B-Sides previously only available in Japan, as well as two unreleased One Day Remains-era tracks "Cruel Sun" and "Solace".
I think most of the rarities have already been released as bonus tracks on other albums, IIRC
They have, either Best Buy exclusives or just bonus in some editions, there are only 2 new never released tracks from the ODR sessions now which leaves one thing unreleased or recorded and that’s On My Way
On Spotify they released The Other Side:
