Pink Floyd ( B3 )

By 1966, the group's repertoire consisted mainly of rhythm and blues songs and they had begun to receive paid bookings, including a performance at the Marquee Club in March 1966, where Peter Jenner, a lecturer at the London School of Economics, noticed them. Jenner was impressed by the sonic effects Barrett and Wright created, and with his business partner and friend Andrew King became their manager. The pair had little experience in the music industry and used King's inheritance to set up Blackhill Enterprises, purchasing about £1,000 (equivalent to £17,100 in 2016) worth of new instruments and equipment for the band. It was around this time that Jenner suggested they drop the "Sound" part of their band name, thus becoming the Pink Floyd. Under Jenner and King's guidance, the group became part of London's underground music scene, playing at venues including All Saints Hall and the Marquee. While performing at the Countdown Club, the band had experimented with long instrumental excursions, and they began to expand them with rudimentary but effective light shows, projected by coloured slides and domestic lights. Jenner and King's social connections helped gain the band prominent coverage in the Financial Times and an article in the Sunday Times which stated: "At the launching of the new magazine IT the other night a pop group called the Pink Floyd played throbbing music while a series of bizarre coloured shapes flashed on a huge screen behind them ... apparently very psychedelic."

In 1966, the band strengthened their business relationship with Blackhill Enterprises, becoming equal partners with Jenner and King and the band members each holding a one-sixth share. By late 1966, their set included fewer R&B standards and more Barrett originals, many of which would be included on their first album. While they had significantly increased the frequency of their performances, the band were still not widely accepted. Following a performance at a Catholic youth club, the owner refused to pay them, claiming that their performance was not music. When their management filed suit in a small claims court against the owner of the youth organisation, a local magistrate upheld the owner's decision. The band was much better received at the UFO Club in London, where they began to build a fan base. Barrett's performances were enthusiastic, "leaping around ... madness ... improvisation ... [inspired] to get past his limitations and into areas that were ... very interesting. Which none of the others could do", wrote biographer Nicholas Schaffner.
