Blind Channel 2027

In February 2021, the band participated in the Finnish national selection for the Eurovision Song Contest 2021 with the modern Nu-Metal track "Dark Side". They won the selection with 54.3% of the vote (the highest in UMK history) and in May 2021 represented Finland in the contest in Rotterdam, Netherlands, finishing in sixth place with a total of 301 points. BLIND CHANNEL received 218 of their total points from televoting, while 83 points were received from juries.

The band painted their middle fingers red for their Eurovision performance of "Dark Side", after being informed that they could not lift a middle finger to the audience onstage due to the show's family-friendly nature. On 19 May 2021, a day before their first performance at Eurovision, the band signed to Century Media/Sony Music. On 7 October 2024, the band announced that they would be going on indefinite hiatus.

On 26 April 2025, Joel Hokka announced he would not be returning to the band, citing insomnia issues. On 5 August 2026, the band announced their return from their hiatus, and revealed their upcoming album, Painstream, which is set for release on 30 October.
