I recently stumbled onto a pair of bands: Son of Rust and VnV Nation. I mention them together because there's a certain musical similarity - though they're not identical by any stretch of the imagination - and because I found them both in the same way: searching random words or phrases on i-Tunes. And, of course, because having found one song (each) that I really liked, I felt compelled to investigate further, and then to buy more of their music.
Both bands feature some wonderful dark imagery, striking lyrics, and (of course) the musical skill to really drive it home. If you aren't already acquainted with them, I'd recommend that you check them out. (The first song I found from Son of Rust was "Strange". The song that hooked me on VnV nation was "Nemesis". In both cases, I had put that particular word into the i-Tunes search bar and was just browsing through the results.)
