Such calamities would have proven insurmountable for 99 out of 100 bands in similar predicaments. Incredibly, Pink Floyd would regroup and not only maintain their popularity, but eventually become even more successful. It was early in the game yet, after all; the first album had made the British Top Ten, but the group were still virtually unknown in America, where the loss of Syd Barrett meant nothing to the media. Gilmour was an excellent guitarist, and the band proved capable of writing enough original material to generate further ambitious albums, Waters eventually emerging as the dominant composer. The 1968 follow-up to Piper at the Gates of Dawn, A Saucerful of Secrets, made the British Top Ten, using Barrett's vision as an obvious blueprint, but taking a more formal, somber, and quasi-classical tone, especially in the long instrumental parts. Barrett, for his part, would go on to make a couple of interesting solo records before his mental problems instigated a retreat into oblivion (see separate entry on Syd Barrett for more details).

Over the next four years, Pink Floyd would continue to polish their brand of experimental rock, which married psychedelia with ever-grander arrangements on a Wagnerian operatic scale. Hidden underneath the pulsing, reverberant organs and guitars and insistently restated themes were subtle blues and pop influences that kept the material accessible to a wide audience. Abandoning the singles market, they concentrated on album-length works, and built a huge following in the progressive rock underground with constant touring in both Europe and North America. While LPs like Ummagumma (divided into live recordings and experimental outings by each member of the band), Atom Heart Mother (a collaboration with composer Ron Geesin), and More...(a film soundtrack) were erratic, each contained some extremely effective music.

By the early '70s Syd Barrett was a fading or nonexistent memory for most of Pink Floyd's fans, although the group, one could argue, never did match the brilliance of that somewhat anamolous 1967 debut. Meddle (1971) sharpened the band's sprawling epics into something more accessible, and polished the science-fiction ambience that the group had been exploring ever since 1968. Nothing, however, prepared Pink Floyd or their audience for the massive mainstream success of their 1973 album, Dark Side of the Moon, which made their brand of cosmic rock even more approachable with state-of-the-art production, more focused songwriting, an army of well-time stereophonic sound effects, and touches of saxophone and soulful female backup vocals.

Dark Side of the Moon finally broke the Pink Floyd as superstars in the United States, where it made #1. More astonishingly, it made them one of the biggest-selling acts of all time. Dark Side of the Moon spent an incomprensible 741 weeks on the Billboard album chart. Additionally, the primarily instrumental textures of the songs helped make Dark Side of the Moon easily translatable on an international level, and the record became (and still is) one of the most popular rock albums worldwide.

It was also an extremely hard act to follow, although the follow-up, Wish You Were Here (1975), also made #1, highlighted by a tribute of sorts to the long-departed Barrett, "Shine On You Crazy Diamond." Dark Side of the Moon had been dominated by lyrical themes of insecurity, fear, and the cold sterility of modern life; Wish You Were Here and Animals (1977) developed these morose themes even more explicitly. By this time Waters was taking a firm hand over Pink Floyd's lyrical and musical vision, which was consolidated by The Wall (1979).

The bleak, overambitious double concept album concerned itself with the material and emotional walls modern humans build around themselves for survival. The Wall was a huge success (even by Pink Floyd's standards), in part because the music was losing some of its heavy-duty electronic textures in favor of more approachable pop elements. Although Pink Floyd had rarely even released singles since the late '60s, one of the tracks, "Another Brick in the Wall," became a transatlantic #1. The band had been launching increasingly elaborate stage shows throughout the '70s, but the touring production of The Wall, featuring a construction of an actual wall during the band's performance, was the most excessive yet.

In the 1980s by decidedly mundane power struggles over leadership and, ultimately, ownership of the band's very name. Since that time, they've been little more than a dinosaur act, capable of filling stadiums and topping the charts, but offering little more than a spectacular recreation of their most successful formulas. Their latter-day staleness cannot disguise the fact that, for the first decade or so of their existence, they were one of the most innovative groups around, in concert and (especially) in the studio. The group began to unravel. Each of the four had done some side and solo projects in the past; more troublingly, Waters was asserting control of the band's musical and lyrical identity. That wouldn't have been such a problem had The Final Cut (1983) been such an unimpressive effort, with little of the electronic innovation so typical of their previous work.

Shortly afterward, the band split up -- for a while. In 1986, Waters was suing Gilmour and Mason to dissolve the group's partnership (Wright had lost full membership status entirely); Waters lost, leaving a Roger-less Pink Floyd to get a Top Five album with Momentary Lapse of Reason in 1987. In an irony that was nothing less than cosmic, about 20 years after Pink Floyd shed its original leader to resume its career with great commercial success, they would do the same again to his successor. Waters released ambitious solo albums to nothing more than moderate sales and attention, while he watched his former colleagues (with Wright back in tow) rescale the charts.

Pink Floyd still has a huge fan base, but there's little that's noteworthy about their post-Waters output. They know their formula, they can execute it on a grand scale, and they can count on millions of customers -- many of them unborn when Dark Side of the Moon came out, and unaware that Syd Barrett was ever a member -- to buy their records and see their sporadic tours. The Division Bell, their first studio album in seven years, topped the charts in 1994 without making any impact on the current rock scene, except in a marketing sense. Ditto for the live Pulse album, recorded during a typically elaborately staged 1994 tour, which included a concert version of The Dark Side of the Moon in its entirety. Waters' solo career sputtered along, highlighted by a solo recreation of The Wall, performed at the site of the former Berlin Wall in 1990, and released as an album.

Syd Barrett, it was reported in the summer of 1996, was lying ill in a Cambridge hospital, unable or unwilling to regulate his diabetic condition. According to reliable sources, Syd has since been doing better. While he did have problems related to the diabetes, he isn't blind as was reported, and continues about his life as usual.
