You probably could have selected 5 of the most popular Lightning Seeds songs and they would have registered as "obscure" for most. But going for obscure songs he produced? That's taking it to a whole new level.
Of these, the only one I knew was Sleeper. (I still can't figure out how Sleeper managed to stick around to make three albums when Louise Werner has such a weak voice...although I do love Shrinkwrapped.)
