Mr. Hat Presents an evening with Melvin Seals & JGB with opening set by Stu Allen at the Mare Island Coal Sheds Waterfront Arts Park in Vallejo. All ages welcome, featuring a spacious outdoor promenade with an interactive Burning Man art exhibit, food trucks, beer/wine/soft drinks, local artisan craft vendors on Shakedown, and a light show by Lya's Liquid Lights. 

Melvin Seals has been a powerful presence in the music industry for over 30 years with a long-established reputation as a performer, recording artist and producer. Melvin is most revered for his powerful, high-spirited, Hammond B-3 organ, and keyboards in the Jerry Garcia Band. Melvin spun his B-3 magic with the Jerry Garcia Band for 18 years and in doing so helped pioneer and define what has now become "Jam Band Music". From blues to funk to rock to jazz, Melvin Seals serves up a tasty mix with a little R&B and gospel thrown in to spice things up.

Melvin and JGB bring an intuitive, expressive style, soul, spontaneity and remarkable chops to the table. John Kadlecik on lead guitar and vocal duties, John-Paul McLean's savory bass, Jeremy Hoenig on the drums and, of course, a heapin' helpin' of the wizard's magic on Hammond B-3 Organ and keyboards. Their chemistry is the focus from which they create a spontaneous and high art where the sky is the limit musically. They will take you on an exciting, psychedelic musical journey that will keep you smilin' and dancin'.
