Pink Floyd (1985)

Roger Waters declared Pink Floyd "a spent force" upon departing in 1985, then sued his former bandmates for the right to use the name, sparking a legal battle that lasted years. David Gilmour and Nick Mason continued touring without Waters, but the feud delayed their next album, A Momentary Lapse of Reason, by 18 months. Compared to #4 Guns N' Roses, Pink Floyd's breakup was more legally vicious, involving 3 separate lawsuits, whereas Axl Rose's solo control created prolonged but less litigious division.
