Re: Albums that grew on you?
It wasn't my first, but Timo Tolkki's Avalon: Angels of the Apocalypse didn't sit well with me the first 3 or 4 listens... then I listened to it and went straight into the Land of New Hope (it's designed to be a 3 album metal opera, part 3, the beginning part, hasn't been released yet) and after listening to it consecutively, Angels really stuck with me. Also, I finally saw the musical direction Timo Tolkki wanted to take on that album and it made perfect sense.
Another album, very recently, that grew on me was Cain's Offering: Stormcrow. I had heard the teaser stuff on youtube and wasn't entirely impressed... Then I heard the full title track. Got on Amazon and ordered the Japanese release faster than Underdog can change clothes. AMAZING album that I haven't stopped listening to for almost a whole month now. Literally, it's almost all I have listened to for a whole month. Album of the year, hands down.
