I agree, start with We are the Tide. I have a feeling that if you start with their first album you might find them to be boring.
I'm not saying that the first album is boring but it is mainly acoustic and really slow. There is room in my musical collection for a few really slow and simple bands and they are one of them. There is something very sincere and heartwarming about their music that appeals to me. We are the Tide includes more instruments and songs with a bit more tempo.
We Are the Tide is instantly gratifying while 3 Rounds might take dozens of listens to fully sink in. I sat on that album for an entire year before I really appreciated it. Both albums are absolutely lovely, though. I really need to see them live soon.
The little I have heard from Blind Pilot didn't appeal to me, but I will definitely give "We Are The Tide" a listen. I was thinking about checking them out in Missoula soon here. I am trying to scratch off potential conflicts, so it won't be so hard to choose when the schedule drops.
