Its hard to say which will be my favorite. I really really liked the new TWY songs but The Front Bottoms are just something else. They are so unique and their new song really picked up where the energy of the last album left off. It will be neck and neck between the 2 for the month. The Marianas Trench EP sounds cool but with 2 tracks from ever after it appears to be a promotional EP geared to boosting album sales and bringing the album to the US. I don't mind though as the new tracks should be cool.
Front Buttz and TWY belong their for sure, but like seriously. The National are one of the most consistently awesome bands and the two songs they've released so far are "good" and "incredible" so like, include them on your list bro.
It's really, really great. I obviously am a fan of the band and I have a very close relationship with them, so I am biased in that sense, but it's just great. Emotional, to the point, and acousticy. It just has that feeling that grabs you.
