there was friction between him (Gil) and the band, but said that despite the occasional arguments, they still remained good friends, and continued to work together on the next two studio albums. Music Echo Park features a varied mix of musical styles. While most of the tracks are fast, with "We Can't Rewind" showing aggression, and demonstrate the change in direction to a more commercial approach, other songs such as "Piece by Piece", "Satellite News", "Turn" and "Oxygen" reveal a quieter, slower and more melodic temperament. With Echo Park, the band began to incorporate additional instruments into their sound. Many tracks feature the use of Moog synthesizers, which Grant experimented with during the recording of the album. The opening track, "Standing on the Edge", is seen by Grant as the most experimental track on the album, as it is mostly synthesized. The closing track "Bug", was recorded live in the studio and uses more dirty-sounding riffs than most of the tracks on the record. The voice heard at the beginning of the track "Standing on the Edge" is that of Matt Sime who is a friend of the band.

The two songs both feature dark moods in the lyrics, with "Oxygen" and "Satellite News" also employing a similar approach. Release Echo Park was released in the United Kingdom on 23 April 2001. Before the album's release, the single "Seven Days in the Sun" reached #14 in the UK Singles Chart, which was the follow-up to "Buck Rogers" which reached #5.

Grant said at the time in a Melody Maker interview, "It's the same with any band. That's just the way the music business is. There is only a certain amount of money a label will put into a band. I'm just being realistic. We've been around for seven or
