Although it wasn't really because of a game I found out about them, they are technically around BECAUSE of a game. So..without the game I may have never listened to the band's music - which would be BAD.

Interview with Midgar (UK Band)

Don't get all anti-FF on me, they don't preach about FFVII and are a really good band. Admittedly one song has blatant FFVII references, but heyho this is what the lead says:

"Midgar" was chosen almost as a tribute to a favourite composer of mine, Nobuo Oematsu. He writes the music for the computer game series Final Fantasy, and when I was younger I was really keen on FF7, particularly for the musical score. I brought the band members together; I knew each of them from various musical endeavours of my own and thought they would be the best men for the job when it came to putting a band together. Fortunately everyone hit it off straight away and we've ended up being a little musical family
