[1] The building of the Union of Composers of Azerbaijan was built in 1912 as a 3-storey property at 27 Molokanskaya Street (now 55 Khagani Alley).

In 1924, sculptor Stepan Erzya was commissioned to make sculptures for the facade of the building.

[3] The lowest level of the statues depicts two blacksmith statues symbolizing strength and intelligence, the middle level depicts a worker and a driller symbolizing the production process, and the highest level depicts an Azerbaijani and Russian worker clinging to a stump, symbolizing the proletarian unity of peoples and the common struggle for the future.

The fact that the worker is a blacksmith and a driller wearing boots and drinking alcohol, as well as having a mustache, means that they are Azerbaijanis.

Due to the lack of marble and bronze, the statues were made of cement and iron remnants with a strong acid content.
