As part of ADEM in 1991, he won a rock festival in Moscow, signing a contract to record in Los Angeles, but due to the coup and the dissolution of the Soviet Union, the band remained in Ukraine.
In May 2015, Andriy and Oleksandr Polozhynskyi, the soloist of the Tartak band, performed for the Ukrainian Armed Forces fighters at the forefront of the Russian-Ukrainian war.
On December 12, 2019, Antonenko was arrested on suspicion of plotting to assassinate prominent Ukrainian journalist Pavel Sheremet on July 20, 2016.
According to the text of the suspicion, law enforcement officers believe that Antonenko, "fascinated by ultranationalist ideas, cultivating the greatness of the Aryan race, dividing society on the principle of nationality, seeking to make their views the object of public attention, taking action to attract public attention... decided to form an organized group to assassinate the journalist and radio host Sheremet".
He was suspected of abusing his official position and deliberately violating the law, making a knowingly unjust decision in a civil case, illegally depriving a citizen of the right to own property belonging to him.
[5] On December 8, 2019, during a pre-trial hearing, Antonenko denied the investigator's allegations and said he had nothing to do with the case, and said: "If it is leaked from me – or on my behalf – that I pleaded guilty, understand that there was torture".
Antonenko also noted that he was born in a Jewish district and that his grandfather was a Polish Jew, so accusations of right-wing or left-wing views are offensive to him.
On December 17, 2019 in Kharkiv near the State Unitary Enterprise of the National Police of the region a concert in support of Antonenko was held.
On December 20, Antonenko filed a lawsuit against TRK Ukraina, Arsen Avakov, Yevhen Koval, Volodymyr Zelensky, and Ruslan Ryaboshapka, demanding protection of honor and dignity.
