Morthen Holmberg has 2 Union Carbide Productions concerts.

Union Carbide Productions was a Swedish rock band formed by Ebbot Lundberg (vocals), Patrik Caganis, Björn Olsson, Per Helm and Henrik Rylander in Gothenburg. Their music can be described as a fusion of psychedelic rock and punk rock — and a bit angrier and closer to stoner rock than The Soundtrack of Our Lives (the band that emerged from the ashes of Union Carbide Productions). Their influences were The Stooges, Frank Zappa, MC5, The Rolling Stones, Love Black Flag, and Minor Threat.
