I was surprised to see Anthology in the list of Ocean Colour Scene's releases, given that it was released barely a year after their Best Of compilation Songs For The Front Row. Granted, Anthology has a disc of B-sides and a couple of extra tracks, but these aside, I'd estimate that this is merely a cynical record-company controlled release to make up for the fact that OCS' last album, North-Atlantic Drift, sold poorly.
So, if you're looking for an Ocean Colour Scene Best Of/Greatest Hits, or if you're an OCS super-fan, you may as well go for this. If you've got Songs For The Front Row, I really wouldn't bother.
