Siddhartha play an interesting style of music that has me thinking of some of the early 90's emo in it's presentation (Think Managra or Embassy). Mid gain guitar work falls beneath some desperately shouted vocals while the drumming seems to dance a bit more, stretching out beneath the songs to add some spice.
There's a lot of melody here as things seem to keep careful attention to creating a whimsical texture of guitars. Even when the band gets on the more aggressive side (see "You Are Not Alone") the music still retains a clarity and seems to sound a bit subdued. I'd be interested to see how this translates in a live setting.
