Across the various different formats, the release of Delicate Sound Of Thunder encapsulates a band at their best. Alongside the classic live album and full concert film (restored and re-edited from the original 35mm film and enhanced with 5.1 surround sound), included in The Later Years box set, all editions feature 24-page photo booklets, with the 4-disc box edition including a 40-page photo booklet, tour poster and postcards. The 3-LP 180-gram vinyl set includes 9 songs not included on the 1988 release of the album, while the 2-CD includes 8 tracks more than its original release. In 1987, Pink Floyd made a triumphant resurgence. The legendary British band, formed in 1967, had suffered the loss of two co-founders: keyboardist / vocalist Richard Wright, who left after sessions for The Wall in 1979, and bass player and lyricist Roger Waters, who had left to go solo in 1985, soon after the 1983 album The Final Cut. The gauntlet was thus laid down for guitarist/singer David Gilmour and drummer Nick Mason, who proceeded to create the multi-platinum A Momentary Lapse Of Reason album, a global chart smash, which also saw the return of Richard Wright to the fold. Originally released in September 1987, A Momentary Lapse Of Reason was quickly embraced by fans worldwide, who flocked to attend the live tour dates, which started within days of the album's release. The tour played to more than 4.25 million fans over more than two years, and, as a celebration of the enduring talent and global appeal of Pink Floyd, was unsurpassed at the time.
