Unfortunately the live performance video and the related source article have been taken down. Below is another version of the theme tune in the meantime...
The release of Mighty No. 9 may still be over a year away on multiple platforms — including the Wii U and 3DS eShop stores — but we can still enjoy the various snippets of content that emerge. Today brings us a live performance of the theme song, which reminds us how important music can be in building anticipation of a major release.
The performance is from composer Manami Matsumae, the highly-regarded former Capcom employee well known for her relatively recent work on Mega Man 10, while she is also contributing music for Yacht Club Games' upcoming Shovel Knight; it's also set for download release on the Wii U and 3DS.
You can check out the live performance from BitSummit 2014 below.
