Crazy Town co-founder Bret “Epic” Mazur issued the following statement:

“It is with profound sadness and heavy hearts that we have learned the passing of our dear friend and brother, Seth Binzer. As the other half of Crazy Town, Seth’s incredible talent and larger-than-life personality left an indelible mark on all who knew him and on the music we created together. Seth struggled with the challenges of maintaining sobriety throughout his life, a battle that he continuously fought privately and publicly. Despite the hardships, he brought immense joy and energy into the lives of those around him. I wish with all my heart that his story could have ended differently, but we find solace in the hope that Seth has finally found the peace he was searching for so desperately all these years. Our Crazy Town family and I treasure the core memories from our younger years, the highs and lows, the laughter and the lessons and each moment contributed to who we are today. Seth’s journey, marked by struggle, was also filled with moments of incredible creativity and love. I want to take a quick moment to stress the importance of sobriety. For nearly 18 years, I have walked a sober path, and I urge anyone struggling to seek help and support, from myself or someone you trust. There is always hope, and a chance for a better tomorrow. We will miss Seth more than words can express. His spirit will live on in the music we made and in the hearts of those who loved him. Our thoughts and prayers are with his family during this incredibly difficult time. Rest in peace, Seth. You will always be remembered and cherished. With love and sorrow….God speed…ya’ boy Bret “Epic” Mazur”
