well, we can't be young and full of energy for our whole lives. aging isn't preventable or reversible. the interesting part is how we adjust.
for the lyricist, it makes sense to move into more reflective, almost hip-hop type territory. yet, la dispute's strength (musically) has always been it's ability to cause a ruckus as the poetry climaxes. the notes didn't matter, it was all atmosphere. they couldn't be separated. as the lyricist softens, the band behind him simply isn't pulling off the shift to sounding like rem very well. the level of melodic introspection simply doesn't match the level of lyrical depth....
sometimes, age brings us closer to our friends as experiences solidify shared ideals and the depth of interests strengthen. other times, we outgrow our friends and move on. the future, of course, remains to be seen. yet, i can't help but think that the band would rather be rocking a little harder, and i'd definitely suggest that the lyricist could benefit from musicians that have a deeper sense of melody.
it's not ironic. it's universal. it's life.
