I ran across this when I was working on that Laki Mera post, and I love it. It's a rare instance of a cover that's neither a mere copy nor a complete transformation--not that there is anything wrong with complete transformation, if it works. Everyone who knows Kate Bush's music at all knows this song, "Running Up That Hill," which is on what most consider her best album, Hounds of Love. It's a very striking song, and Kate's voice was of course pretty spectacular back then, and the big arrangement, with lots of multi-tracked vocals, is very effective--the whole thing is just big, a movie on the big screen (although according to Wikipedia it's all done by five people, counting Kate). It sort of demands to be played loud.
Here Laki Mera make it intimate without really changing anything. Laura Donnelly's performance exemplifies what I like about her singing: it's soft but not weak, not overtly expressive but still somehow full of feeling. You might call it restrained in comparison to Kate, but it doesn't feel constrained. Instead of a cry of passion it's a gentle word, but the emotion is still there.
The song seems to be a sort of musing on the strangeness of the male-female difference, and the fact that neither can know what it feels like to be the other, in the sex act but not only there.
If I only could
I'd make a deal with God
And I'd get him to swap our places
I guess I should include the original, in case you don't know it.
