Kontsert (/kɒntˈsɛərt/; Russian: Концерт, [kɐnˈt͡sɛrt]; commonly read as Kohuept or Kohliept, English: Concert) is the second live album by Billy Joel, released in 1987.

While performing "Sometimes a Fantasy", the audience kept getting attention from spotlights, which angered Joel as he felt it was making it harder to connect with them, because crowd members on whom lights shone would suddenly become silent and still.

He then trashed his instruments, overturning his piano and breaking his mic stand; neither he nor the band stopped performing despite this.

The implementation of Gorbachev's glasnost allowed people of the Soviet Union to witness Western rock.

[9] While in Russia, Billy Joel and his daughter Alexa met and became friends with a clown named Viktor.

The B-side was "The Times They Are A-Changin'", Joel's live cover of Bob Dylan's song.

In addition, the DVD/Blu-ray set contains a newly produced documentary of the same name which features updated interviews with Joel's current and former band members as well as personnel involved with the original 1987 production.

"Superfans are likely to drool over the deluxe edition which includes a book with accounts from writers and journalists who were on the road with Joel during the tour," Charles Pitter at PopMatters wrote.
