Please answer the following question: Given the following context:  Big Star was an American rock band formed in Memphis, Tennessee, in 1971 by Alex Chilton, Chris Bell, Jody Stephens, and Andy Hummel. The group broke up in early 1975, and reorganized with a new lineup 18 years later following a reunion concert at the University of Missouri.  In its first era, the band's musical style drew on the Beatles, the Rolling Stones, and the Byrds. Big Star produced a style that foreshadowed the alternative rock of the 1980s and 1990s. Before it broke up, Big Star created a "seminal body of work that never stopped inspiring succeeding generations," in the words of Rolling Stone, as the "quintessential American power pop band," and "one of the most mythic and influential cult acts in all of rock & roll".Big Star's first album—1972's #1 Record—was met by enthusiastic reviews, but ineffective marketing by Stax Records, and limited distribution stunted its commercial success.

After a third album, recorded in the fall of 1974, was deemed commercially unviable and shelved before receiving a title, the band broke up late in 1974. Four years later, the first two Big Star LPs were released together in the UK as a double album. The band's third album was finally issued soon afterward; titled Third/Sister Lovers, it found limited commercial success, but has since become a cult classic. Shortly thereafter, Chris Bell was killed in a car accident at the age of 27. During the group's hiatus in the 1980s, the Big Star discography drew renewed attention when R.E.M. and the Replacements, as well as other popular bands, cited the group as an influence.
