It's a Disco Night (Rock Don't Stop)
"It's a Disco Night (Rock Don't Stop)" is a 1979 club hit for The Isley Brothers, released on their T-Neck label as the second single from their gold-certified album, Winner Takes All. The song is notable for being one of the few disco-based songs the Isley Brothers released. Beforehand, the group were known for their mixture of funk, rhythm and blues and rock. The song was led by brother Ronald Isley while his brothers Kelly and Rudolph Isley chanted "rock don't stop" in the background. The song briefly charted on the Billboard Hot 100 peaking at number 90, hitting number 27 on the R&B chart. Outside the US, "It's a Disco Night" reached number 14 on the UK Singles chart.
