«The Largest Prime Number» (SBP4) are veterans of the Russian-language indie scene.

A smart and fun indie band with a 20-year history, they've navigated an incredible maze of genres: post-hip-hop, ambient, IDM, indie pop, and much, much more.

Over this long period, SBPC has released 15 full-length albums, as well as countless music videos, singles, remixes, and collaborations.
Their history has included everything, except perhaps tours in America and Canada.

Kirill Ivanov, creator and frontman of the group:

“We are currently writing a new album, hopefully the most danceable in the band’s history.
And we will definitely play new songs.
And also rare, unexpected and the most famous!
So invite your local friends to our concerts: it’s even easier to get into the songs when you don’t know the language.
We are very happy and really want to see you all!”
