Now before you crucify me i'm doing this for the same reason (I think) that rags is; to show some good modern music!
So first off:
August Burns Red: Yeah yeah you probably know them, but they are awesome and definately worth a checking out. Some good melodic metalcore with very good vocals, and very high production recording on their cymbals :P Makes their breakdowns sound incredibly sexy. Sexiest drums ever. Composure.
Beneath the Massacre: This is my limits basically, i'm not even really sure if I like them haha, maybe just a tad too heavy for me at the moment very technical grindcore stuff, very heavy but good when you're in the mood. (no, not THAT mood...) Societys Disposable son.
Belay My Last: Kinda generic but fun nonetheless, an amazing vocalist quite similar to Johnny Davy of JFAC. One More Foot in The Grave.
Born of Osiris: Now, I've already shared this masterpiece with Rags but they're my favourite band at the moment. Odd timings, excellent recording, great vocals, skillful instruments and awesome keyboards make this band really unique and all round great. Amazing breakdowns also. Open arms to Damnation.
Ion Dissonance: Really not for everyone, odd timing, tempraments and tunings; quite heavy but I love it. The drummer is insane and the breakdowns are off time so you know they're catchy! Kneel
Misery Signals: Amazing melodic hardcore with a lot of odd timings and sweet soft parts. Nice breakdowns and an emotional vocalist, these guys hit hard for me. The Failsafe.
Necrophagist: Once again pushing my limits but good guitars to listen to. German death metal with some more odd timings and insane solo's that are probably the best part. Stabwound
Symphony in Peril: You've probably heard the all famous breakdown in youtube video's such as "Drive by hardcore dancing" and what not, but they are a great band and a big shame that they broke up. (Only video I could find that showed the song) Stiletto.
The Faceless: An all time favourite of mine, another technical band with great keyboards and breakdowns. Not much more to say than that but they pwn! Leica
