Liars - Drum Gets a Glimpse

The song that I chose to analyze is Drum Gets a Glimpse, by the British group Liars off of their album Drum's Not Dead. The lyrics of the song are as follows:

It seems like all our friends are gone.
You drove them out.
Was I naive to think they'd stay?
You were a bore.
Why can't we just try start again?
It just won't work.
There's so much that we couldn't say.
You speak in tongues.
I'm bothered by these trembling stars.
Then close your eyes.
Why should we try to stay awake?
'Cause you can't sleep.
Then why should I be here at all?
'Cause you can't sleep.

Drum Gets a Glimpse is written as a dialogue between the album's two character's, Drum and Mount Heart Attack. Drum is the first voice, and is optimistic about his new ideas and activities that he introduces to his companions. Mount Heart Attack reacts to all of Drum's doings, telling him why they do not work and why they are wrong. Drum's ideas, rather than creating a positive effect amongst them, caused a riff, which in turn led to his isolation, suggested in the opening lines. These ideas come from a source external from their traditional origins, this is hinted at by Mount Heart Attack who tells Drum that he "Speaks in tongues." Drum, in this case, represents the introduction of foreign ideas into a harmonious system and this can lead to splintering. Mount Heart Attack looks to explain to him that although he thought that these ideas were going to help, they ultimately just caused turmoil and grief.
