Polish death metal act Hate are in mourning after the death of their bassist Slawek 'Mortifer' Archangielskij. The musician passed away near the German town of Munchberg on the night of April 5 while the band was en route to their next gig on their European tour.

Hate, who had been on the road in support of their latest album, 'Solarflesh,' posted about the loss of their comrade and stated that they'll immediately stop their current tour as a result of his death. Archangielskij was also the bass player for Naumachia and the guitarist for Saltus. Both of those bands reposted Hate's original Facebook message on his passing on their sites as well.

The posting on the bassist's death reads as follows:

SŁAWEK „MORTIFER” ARCHANGIELSKIJ IS DEAD At night 5th/6th April near a German town of Munchberg, our friend, best comrade and longtime bass player unexpectedly passed away. After the show in Stuttgart last night he went to sleep and never woke up. We found him lifeless early in the morning and immediately called an ambulance. He was reanimated, but to no avail. Results of Sławek’s autopsy should be known soon. In this situation, we decided to cancel the remaining shows and return home. We gave detailed testimonies to the German police. We are shocked and shattered by his sudden, unexpected death. We mourn together with Slawek’s family and friends. Adam, Konrad, Stanislaw, Daniel /HATE

The death metal act has been around since 1990, but has gone through a number of bassists since their start. Archangielskij had been a touring member since 2007 and an official band member since 2009. Frontman Adam "ATF Sinner" Buszko remains the band's only original member. 'Solarflesh' is Hate's eighth studio album. Watch the video for 'Alchemy of Blood' from Hate's 'Solarflesh' album below:
