Here are some fragments from an on-stage interview with Hogarth and Pete
Trewavas, that was done before the album was released:

(To Pete:) "Can you describe the new album?". Pete starts talking about the
music: "Brave" is gonna be a concept album like Misplaced_CH, one long
piece of music. Quite specific, he said it was gonna be 64 minutes (yeah!).
It has 19 tracks, some of which are just bridges between the real songs.
And there are no hitsingles on it, they're pretty much doing what they
want.

(To Hogarth:) "What's the album lyrically about?". Hogy tells a long story:
He lived in Bath (I think it was) for a while and one day he heard a police
message on the radio. The police had found a young girl wandering on a
highway bridge (which is illegal). The girl was in some kind of shock
and wouldn't talk at all, so the police didn't know her name. That's why
they were asking on the radio if anybody knew that girl. This what the
album is about, Hogy said he was very touched by this. And before he gave
back the microphone he said "and may I add that this is just gonna be
he best piece of music we've ever made!".

Initially the title of the album was "Severn", as the highway bridge
mentioned above was a bridge over the river Severn.
