Oh, wow. There are older bikes branded Soma -- I think it was one of the 80s Japanese manufacturers, and I've seen mixtes from that older Soma brand on eBay. But that is the current Soma logo! I have no idea how old that is but it's a sharp looking bike.

It looks more upright than the Buena Vista, though. And the Buena Vista only comes in white. Must be an older frame ... did they ever do custom work?
