Master Rock Studios, Kilburn, London. The rehearsals were very tense and would inevitably split the band into two separate camps. Butler had his own agenda, and he frequently clashed with the rest of the band and producer Ed Buller, over whom he had concerns during the recording of the first album. According to Buller, Butler and the rest of the band were not in the studio together once during recording, perhaps only for a matter of hours. Butler seemed to antagonise his bandmates further when he appeared on the front cover of Vox magazine under the tag line "Brett drives me insane." In a rare interview, in that he only ever would do press interviews on the pretext it was about guitars, he said of Anderson: "He's not a musician at all. It's very difficult for him to get around anything that isn't ABC." A despondent Anderson remembers reading the article the same morning he was recording the vocals for "The Asphalt World": "I remember trying to channel all this hurt that I was feeling and the iciness I was feeling into the vocal." Butler later apologised to Anderson over the incident. Musical differences over "The Asphalt World" triggered the next dispute. The version that made it on to the album lasts for nine minutes 25 seconds, but according to bass player Mat Osman, Butler's initial creation was a 25-minute piece with an eight-minute guitar solo. Osman felt that Butler's compositions were too audacious and experimental: "Lots of the musical ideas were too much. They were being rude to the listener: it was expecting too much of people to listen to them." The original extended version was in fact 18 minutes long and had to be cut in half (although this long version was, according to Anderson, composed in pre-production and featured only guitar and drums, and was intended to be edited; hence the original version is just over 11 minutes long). Butler had been writing lots of additional minor pieces, and was absorbed in complex arrangements. He was interested in progressive rock, and during this time appeared in a BBC programme about Pink Floyd. The extended "The Asphalt World" and the experimental ending for "The Wild Ones" were borne out of this affinity. Both would later appear in the 2011 expanded edition. The arguments over "The Asphalt World" spilled over on to the rest of the album, as Butler
