They won a Grammy for a track, not the album itself.
“Marooned” — the instrumental from The Division Bell — won Best Rock Instrumental Performance at the 1995 Grammys. The album itself didn’t take home any major awards, which feels about right for a mid-career Floyd album that’s good but not Dark Side.
People remember The Division Bell as the “comeback” after a decade of lawsuit drama, but it’s not their most decorated record. The Grammy for that eerie, slide-guitar-heavy instrumental is the one piece of hardware it got.
