"can lead you into dark places", while "Banquet" details "how sex is about power, submission, domination and real rapacious desire". The lyrics in the chorus of "She's Hearing Voices", "Red pill / Blue pill / Milk of amnesia", are in reference to the medications a friend of Okereke's took to relieve the symptoms of schizophrenia. The lyricist has described the moment in "This Modern Love" when the backing vocals enter the mix before the second chorus as "perfect", because it evokes the idea of "two people on the telephone, who can't touch each other, and as the song and the conversation progress, everything amplifies". Promotion and release Bloc Party EP was distributed in America in September 2004 by Dim Mak Records, while the band performed several gigs at the end of the year in the US and Canada.
