Band is not good. They seem like they have huge ego's. this "double ep" thing proves my point. They feel they must be original and different. What is considered an ep to them 4-6 songs? So pretty much they could make a full album with two. Even if they pulled a Thrice and had them themed it could still be a full album. Their dumb. The end.
they're not the first band to do the "double EP" thing instead of doing one album. some bands feel like there's a significant difference between 2 groups of their material, and they'd rather split it in half and have it be more cohesive than throw it all on one, lack-luster album without any real definition.
2 of my all-time favorite EPs, released in the same year, but they would NOT have made a cohesive full-length in my opinion.
so really, i don't think this is that weird of an idea and i certainly don't think it's a reflection of whatever egos they may or may not have.
