I'm working on the logo & wordmark for a company that will be based online (it's a music service) and aimed at Churches, primarily older and smaller high-churches, like Presbyterian, Episcopalian, Lutheran, etc.

Currently I'm using Proxima Nova or Gotham in the mockups (anyone want to weigh in on why I should pick one over the other?), set in all-caps, but I'd like to see something that looks a tiny bit more traditional. I'm thinking some slight serifs or something. Normally I'd try to solve this with a slab serif like Adele or PMN Caecilia, but it ends up looking too tough, and most serifs just look too boring to be used for an online music service.

So I'm looking for some suggestions... Like I said, something current and contemporary is key, but with some sort of throwback to older styles, and preferably a wide letter form in the uppercase. It's be a plus if the typeface had some neat little quirk that gave it a personality as well.

By the way, if I stick with a serif, I also thought about Eigerdals (http://new.myfonts.com/fonts/insigne/eigerdals/), the bold weight in particular... anyone have any thoughts on that font or the foundry?
