Well, Vesper sounds like a bitchin' band name, actually. Lol. Here's some more I can think of at the top of my head:



Elixir

Tachyon

The Roar

Unequivocal Relentlessness

Ivory

The Blueprint to Madness



But mostly, these probably won't work.. The best band names usually come from a common goal/word that has meaning to all of the members. It all just... clicks, and it'll happen in time. Hell, it took me and my band about a good 4-5 months to agree on a band name -- but once it was out in the open, it was clear that it was definitely the best name for us.
