Besides the Big Singles, I don't think Joshua Tree is anything special.
'Red Hill Mining Town' says hello. So does 'Running to Stand Still'. So does 'One Tree Hill'. So does 'Mothers of The Disappeared'. Oh, so does 'Bullet the Blue Sky', lol. And we're still forgetting about killer tracks like 'In God's Country' and 'Exit'!
Even just listen to 'Red Hill Mining Town' after listening to anything from the last 4 albums and tell me it doesn't resonate on a deeper level. I mean, this is 'Red Hill Mining Town' -- an almost forgotten track off the album -- and it still sounds like a classic.
