Is it reasonable that I think of HEARTSREVOLUTION as a product that was brought to market after Crystal Castles kind of carved out the niche for people to be into 'electro-bands that consist of a male and a female'? I remember after Ladytron was a hit, there was kind of a supersaturated market of 'electro bands with female lead singers that sang about the night/drugs/sex/etc.' Now I think Crystal Castles has kind of inspired a tolerable mini-renaissance for this type of act.
I have haven't really listened to Heartsrevolution very extensively, but I think they are probably one of the most [highly documented] bands not named "JUSTICE" in party pics over the past 6 months. People who seem to know a lot about electronic music are pretty high on the remixes of their songs.
1. Which do u like more, hoodies, or masks?

Hearts Revolution might have given up the mask thing, or only used it for promo pix. However, Crystal Castles have somehow managed to transition from the 'angsty, dark teenager' hoodie aesthetic, over to the 'we are in a touring electro-band' aesthetic.

When will GAP make a hoodie ad-campaign and utilize Crystal Castles?
EDGE: CRYSTAL CASTLES
2. Who has better t-shirts/design visuals?
There's no way Crystal Castles can win this category after coming under so much scrutiny for 'stealing' the Chanel logo and their Madonna artwork.

The Choosing Your Own Adventure vision test t-shirt may or may not be one of the most memorable t-shirt metaphors of 2008.
EDGE: HEARTS REVOLUTION
3. Which female singer does a better job of applying eye makeup?
Alice from CC applies a heavy coat of black eyeliner, but the pink mask effect might put the HEARTSREV broad over the edge. Do yall think Alice was a Graveyard Girl in HS?

Edge: Hearts Revolution
4. Which band is more cryptic without being too annoying?
Do you know any one that actually knows the lyrics to Crystal Castles songs, and sings along while they drive their Volkswagon? I think it's pretty interesting how CC managed to make songs that 'sound interesting' enough to distract people from having lyrical expectations. It's like they have three or four 'distinct synths' that they just stuck to using.
On the other hand, one of the most memorable lines of HEARTSREVOLUTION's proudest song is
'foxes and bunnes/fire and snow/we are all just lost/don't which way to go.' Maybe I'd like it more if it was 10x more distorted, and I couldn't quite understand what they were saying.
HUGE EDGE: Crystal Castles
5. Which male member of the band does a better job of pretending to do something while playing live?

I've read on a lot of internet message board blog rumormills that Ethan from Crystal Castles is great at chilling on stage. The secret is that your body needs to crouch over your gear so that your body forms an angle that is smaller than 135 degrees. The closer to 90 degrees, the better.

Here's the Heartsrevolution guy

I don't really have an issue with people who 'don't play instruments live.' We can't all be as charming as Dan Deacon.
Edge: TOSS UP
6. Which band is more likely to have a song featuring Cory Kennedy?
Oh. HEARTSREVOLUTION already did that? Cory Kennedy can do everything!
HUGE EDGE: Heartsrevolush
7. Which is more likely to be driving an ice cream truck in 2 years after the implosion of the 'blog house' genre, and every one is into lofi and acoustic post-existential music?

Since Heartsrevolution is apparently more of a 'lifestyle brand' than a band, and they already have job experience driving ice cream trucks, we can assume that they have a head start on getting back into the truck again. However, Crystal Castles could always be the creepy van-with-no-windows that drives around your neighborhood selling only ice cream sandwiches and push pops.
SLIGHT EDGE: Hearts Revolution
8. Which 1 is better?
It's tough to really say. Every1 prefers different stuff. We're all different, so maybe we should just all unite, and have a good time, and be friends with every one. Let's build a scene that's all about positivity, and stuff like having fun and partying and stuff like that.
EDGE: It depends on what ur in2
