The way i look at it is this. 50% of your stuff has to be very stylistically similar and have a clear focus of what the band is about. 25% can be to the left of that spectrum, and the other 25% to the right. So the songs that are furthest away from the center on the left and right may not sound similar at all, yet they are both connected in some way to the core sound. The Beatles did this from album to album. Your mother Should know and I Want You She's So Heavy couldnt sound less alike yet they both sound like The Beatles. A modern band that does this quite well is the Foo Fighters. It all sounds like them but maybe not so much song to song. I am not a fan of bands who sound like they keep doing the same song over and over. Alice and Chains seemed to go to the same well once to often for me, although it is a distinct sound and super recognizable it was real easy to get tired of the parrallel harmonies. Dirt is an amazing record though for that style of music.
