2015 - present
On May 19, 2015, the album "Here and Always" was released. During the recording of the album, members of the group "Tantsy Minus", guitarist Anton Khabibullin and drummer Oleg Zanin, joined SBPCh on a permanent basis.
In September 2016, the album "We Are a Huge Animal, and We Will Eat You All!" was released, which Afisha magazine rated 7.5/10.[12] The album presentation took place in November at Moscow's Izvestia Hall as a large-scale concert-performance.
In 2017, the maxi-single "I'll Throw Away My Head—Let My Heart Think!" was released online, and the film "About Love. For Adults Only" was released in Russian cinemas. In one episode, the band appeared and performed the song "There," with the refrain "Yesterday everything was fine, today you just fell in love."
In the spring of 2018, the album "We Didn't Sleep, We Dreamed" was released, featuring singer and actress Zhenya Borzykh as a full-fledged member of the band. Nadya Gritskevich, Thomas Mraz, and the St. Petersburg Children's Choir of Television and Radio also contributed to the album. Former Pompeya keyboardist Alexander Lipsky served as the album's sound producer.
After recording this album, Ilya Baramia left the band and focused on the hip-hop duo "Aigel." Stanislav Astakhov took his place.
The band "The Biggest Simple Number" continues to work on new compositions and perform. By early 2022, they had accumulated enough new material, and on November 4, they released the album "Nothing Else." Musician Kirill Ivanov called the album a premonition come true and expressed hope that it will provide support to those currently suffering.

In 2012, the album "Forest Oracle" was released, inspired by summer vibes, particularly during his time at the Kamchatka children's camp, where Kirill Ivanov occasionally worked as a camp counselor. A music video for the album's title track, "Ideal Place," was also filmed there. Drummer Alexandra Zakharchenko also contributed to the album.

SBPCh performing in Israel in 2024
The split album "SBPCh and Cassiopeia Sing Each Other's Songs," released in 2013 as a limited edition on red vinyl, is the last recording to feature Alexander Zaitsev. Afterward, the band consisted for a time of Kirill Ivanov and Ilya Baramia, who occasionally invited outside singers and musicians to contribute to the creative process.
On March 3, 2014, the album “I Think They Didn’t Invent a Word for This” was released, with musician Igor Vdovin and singer Nadya Gritskevich involved in the recording.

The newspaper Trud, which called Baramia and Zaitsev the ideological successors of Sergei Kuryokhin from the group Pop Mekhanika, wrote about Kirill Ivanov: "It's difficult to define what he brings to the stage—it's probably something between a reading and a melodiously recitative performance, combined with a musical backdrop. His lyrical hero is a unique anti-macho: a frightened boy, slowly maturing and gradually losing his childhood."[7]
Whether consciously or not, in the second year of his project, Kirill suddenly took a step worthy of Kuryokhin himself: he asked the audience to bring their own children's pipes and metallophones and improvise with the performers during the concert. And with this bold move—for the first time in Russian pop music—he completely eliminated the boundary between stage and audience.

• Labor
  In 2008, the band members, together with fellow musicians, launched the "SBPCh-Orchestra" project. They recorded an album of the same name, featuring 17 different musicians: from Stas Baretsky to Larik Surapov, ObshchezhitiE, and Klever. The album "SBPCh-Orchestra" was released in November 2008.
  The spring of 2009 marked the return of the trio. SBPC departed from their original IDM genre: Ilya Baramia took up bass, and Alexander Zaitsev became the guitarist and co-vocalist, sharing equal terms with Ivanov. Some of the new material was presented at concerts and as several singles, but the third album wasn't released until November 12, 2011.[8] Since then, the band has strived to release a full-length album per year, while Kirill Ivanov himself has retired from journalism and devoted most of his time to the creative process.

2006–2007: Formation and first album
In 2006, journalist Kirill Ivanov met the duo "Yolochnye Igrushki" (Yolochnye Igrushki) and showed them his musical material (then defined as post-hip-hop, anti-hip-hop, and deconstructivist hip-hop), which he had been working on in his spare time. Kirill, as part of "2H Company," gave his first performances with this material. Their first performance in Moscow took place at the "AVANT 2006" festival. In August, Kirill performed at the "Nashestvie" (Invasion) festival, after which the decision was made to record the new project's debut album.
Initially, the group was called "232,582,657 - 1," and this notation was the largest known prime number at the time. However, the current name was later adopted as new largest prime numbers were discovered over time.
[This number] is something very large, something difficult to understand, and at the same time extremely simple and clear – that's mathematics, after all. By and large, all the most important experiences and sensations are exactly like that: powerful, complex, and yet simple, instantly recognizable, unmistakable.
Kirill Ivanov
By 2007, the first album was ready and distributed through friends. The recording reached the renowned musician and producer Oleg Nesterov, who officially released it on his label, Snegiri.
For several years after the formation of the project "The Biggest Prime Number," Kirill Ivanov continued to work as a journalist, producing stories for the programs "Glavny Geroi" (NTV) and "Bolshoi Gorod" (STS). It is noteworthy that for one of the stories on the latter program, which discussed the Grushinsky Festival, Ivanov wrote a song that was performed at the festival by TV presenter Tatyana Arno with the support of Alexander Zaitsev.
