The Blood Brothers for most people are a love/hate band. I really don't care for them. Their music isn't half bad, and the guy that screams fits right in. However they have a guy that sings like he's a retarded reject from ICP wich ruins every song. If after you hear them and decide that you like them, check out the bands Soiled Doves, Chromatics, and I forget the name of it but it's a side project of the blood brothers with the yeah yeah yeahs.
As far as emocore goes...
A few other bands worth checking out are:
Monday In London
This band isn't for everyone, I'll say that upfront. However they have an amazing twist on typical emocore. The lead singer seems to really be lost in his own world. Everything about their sound is new, and perhaps that's why they never got much exposure. Their album "The Red Machine" is awesome all the way through. You ever heard that song by trapt "lost in a portriat" well that's what Monday In London sounds like.
Matchbook Romance
This band has that real "sonic" sound to them kind of like yellowcard or lost prophets. The screams on thier album are turned down so you only hear them in the background. Theres two vocalist (who often trade parts back and forth) Some songs worth checking out are Shadows like Statues, Stay Tonight, The Greatest Fall Of All Time. (Theres plenty more but I forget the titles)
Adair
A really great band live, a great band on cd. I don't have anyone to really compare them to. Check out the songs Afraid To Breathe, The Diamond Ring, The Ghost Of Who You Were, & Seatbelts Let Go
Superstitions Of The Sky
This is actually just an emo band. However they're the best that the "emo scene" has to offer. If you like old silverstien, then this is deffiniatly a band for you.
Straylight Run
Again another band that sounds very similiar to Silverstien. Just add a touch of Postal Service and I'm sure you can imagine the sound.
