Here's something to check out: Concerts playing orchestrated arrangements of game music!
Of course, they're not all
that new, but I'm sure some people here didn't know of their existence.
Some of these godly arrangements below:
Super Mario Bros./World/64Sonic the Hedgehog 1Chrono Trigger/Chrono CrossFinal Fantasy VI-Dancing Mad <-- Look at the size of that organ here!
*If the choral part of the FFVI arrangement sounds a bit echoey, it's just due to the camera's mic and the walls.
There's a lot more arrangements out there than this, but I couldn't be bothered to post it all.
Also, a note for anyone in the DC area: PLAY! will be held in Baltimore on July 18, 2008. Tickets are being sold for $30 and up, but it won't be long before all seats are taken, so if any of you want to go, you'd better hurry!
