Tre Cool from Green Day side project called Dead Mermaids. They are Icelandic Metal šŸ¤˜ and Tre Cool is the lead singer. He even had some lyric sheets out on the stage. I got photos of those below also. This was recorded live at the Tiki Bar in Costa Mesa, CA on Jan 20th 2018 on YouTube live. There were a small amount of vinyl that was sold at the show. Hopefully one day their music can be on iTunes like Pinhead Gunpowder and The Frustrators. I was luckily enough grab a photo with him before he got all dressed up. The band was actually a lot of fun live. Live pics below also for your enjoyment. By @SteveSievers
