I really don't know much about it and have never heard the band before this. I just came across this during my AM blog check. The style of music isn't much of my thing, but I will definitely check out the lyrics to see if they can be worked into regular rotation.
It is really impressive though, they have really stepped up the game for both bike touring (or maybe this is a commuting/touring hybrid of some sort) and band touring.
I think about how much my amplifiers weigh and I don't think this would be possible without some serious compromises in the amps one takes on tour, though I think if the PA were to power even the guitars it would be workable. One speaker each for two members, the amplifier/mixer for another and then all the cables/stands/etc for the fourth. I definitely think it would be fun. I wonder how they dealt with the rain?
