Oleg Savchenko was born on July 10, 1989 in Vitebsk, in a family of journalists. He started playing music as a child when his father hired a piano tutor for him. But later he dropped out and started writing his first poems.

The first performer whose songs Oleg liked was Andrii Gubin. At the age of 14, he watched the TV program «Фабрика звёзд 4» (Star Factory 4), in which Timati acted. This impression made him interested in hip-hop culture, and he became a listener of Detzl and Bad Balance. Later, he got acquainted with Russian rock and the work of such musicians as Земфира (Zemfira), Найк Борзов (Naik Borzov), «МультFильмы» (Mul'tFil'my), «Мумий Тролль» (Mumiy Trol') and «Король и Шут» (Korol' i Shut). However, he later returned to hip-hop, starting to listen to American hip-hop, from which he gained experience and concluded that «the sound is as important as the meaning, and sometimes it can be more important».

He graduated from the Faculty of Philology of MLU with a specialty of «linguist-teacher». Oleg recalls that at that time he often faced financial difficulties. But his parents always supported both him and his musical endeavors.

In 2011-2013, LSP began his career with the release of a video clip for the song «Хиппи» (Hippie) and the release of his debut solo EP «Видеть цветные сны» (See colored dreams), which featured Aes Genius, 614, Paul Pain, and LSP himself. Roma Anglichanin, a well-known producer, was responsible for the overall mixing control of the release.

After the release of the single «Номера» (Numbers) in 2012, close cooperation began between LSP and Roman Nikolaevich Sashcheko. In 2012, Oleg also participated in the A-One Hiphop Battle, although the whole year was devoted to self-education and prioritization.

In 2013, LSP released several popular tracks, including «Больше денег» (More money), «Лилвэйн» (Lilwayne), and «Коктейль» (Cocktail), which became one of the best songs of the year according to rap.ru and the A-One channel. He also performed cover versions of the songs «Дурак и молния» (Fool and the lightning) by the group «Король и Шут» (Korol i Shut) and «Truth Gonna Hurt You» by American rapper Future, and also released several of his own tracks, including «Сити» (City), «Потерян и не найден» (Lost and not found) and «Пикачу» (Pikachu).

In 2015, LSP released the EP Romantic Colegtion and the album Magic City, after which he ended his collaboration with Booking Machine. Romantic Colegtion included two new songs produced by Roma Anglichanin and an updated version of the track «Именно такой» (That way) featuring Deech and Maxie Flow. The song «Силовое поле» (Force field) was noted by The Flow as one of the best Russian-language songs of 2015, and LSP himself called its lyrics one of his best creations.

The Magic City album was released on July 19, 2015. Roma Anglichanin was responsible for the production and post-production of the album, with guest verses provided by PHARAOH, Oxxxymiron and Sil-A. In anticipation of the release of the album, a video was released for a remix of the song «Безумие» (Madness), recorded with Breezey Montana. After a failed joint project, the songs from it were completed by Oleg alone and included in the Magic City album.

At the end of the year, The Flow placed «Bullet» (with PHARAOH) and a remix of «Безумие» (Madness) (featuring Oxxxymiron) in the list of the best songs of 2015. Also in 2015, a music video for the song «OK» was released.

In the summer of 2015, LSP ended its partnership with Booking Machine, explaining that the number of concerts had decreased.

In 2017-2018, rapper Oleg Savchenko continued his musical tour Tragic City Tour in support of his album Tragic City, despite the tragic death of his friend and producer Roma Anglichanin. He also announced that the LSP project would continue to exist. The new live line-up of LSP includes Den Hawk and Petr Klyuev, known for their collaboration with Oleg in the early stages of his career.

On October 2, 2017, LSP released a video clip for the song «Тело» (Body), dedicated to the memory of Roma Anglichanin. On the same day, he became a guest in the «Vecherniy Urgant» program, where he sang the song «Лабиринт отражений» (Labyrinth of reflections). The role of Roman Sashcheko in the video was played by video blogger Dmitry Larin, and the backstage from the filming was published on his channel on October 4. The song «Маленький принц» (The little prince), which was also written in memory of Roma Anglichanin, was released on December 14, 2017, and the Hell and Back tour (2018) was also announced.

On February 28, 2018, LSP released a video clip for the Face «Бэйби» (Baby) remix, where the Belarusian video blogger Pleasant Ildar played the main role. The video was filmed in August 2017. The original idea was that LSP and Face would release their videos on the same day, creating a contrast. However, Face abandoned this idea and released a video for the song «Я роняю запад» (I'm dropping the west).

In July 2018, a significant event took place in Oleg's life when he married Vladislava Amelkova, with whom they had been in a romantic relationship for a long time. Preparations for the wedding took about two weeks, as a result of which the ceremony was successful in the circle of relatives and friends. After that, the happy spouses were waiting for replenishment in their family, and on February 16, 2019, daughter Ariana was born.
