I'm hesitant in using the word "pop" in my title, but I'm sorry, New Pornographers encapsulates just that sound. It may not be for everyone, and it may not even be the "pop" some may think of (boy band groups, Michael Jackson, etc.), but it is extremely listenable music. And it's from an indie label. Therefore, I label it "indie pop."
Okay, so with that said, Electric Version is a conglomerate of talented musicians coming together to create a sound that's not necessarily new; it's only just being re-introduced to the 2000's. It's sort of a mixture of different types of 60's retro pop mixed into the rock music of today. Think of The Shins, think of The Lilys, think of The Wrens, think of any band that uses an organ as a main instrument....
The mixture of male and female vocals is usually not one of my favorites, but with The New Pornographers, it really works. I think it's more because of Neko Case being the female singer than anything else. Either singer could certainly sing on the CD independently, and it would still be a great release.
I think any fan of some of the abovementioned bands would love The New Pornographers. In 2004 I can't say it's certainly a fresh "new" sound for music today (seems there has been more of an influx of this same sound since Electric Version's release), but if you're trying to discover another band that fits the bill, then The New Pornographers is one for you. The more I listen to it, the more I love it.
