Coronel created the riff and chord structure of "She" and "Goin' Blind", co-authoring the songs with Simmons. A former member of The Long Island Sounds (with Seth Dogramajian), Bullfrog Bheer, Tree (with Paul Stanley), Cathedral, Coffee, Rainbow (unrelated to the Ritchie Blackmore band of the same name) and Wicked Lester, he introduced Gene Klein to Stan Eisen in Steve's Washington Heights apartment. Wicked Lester later became Kiss, when Simmons and Stanley decided to start a new band. Coronel then formed the band Lover. He continues to work with music and also design. He has done for instance showrooms and expos for clients such as Canon Inc. in 2010.
