Penn’s Peak will be rocking this weekend.

On Friday Melvin Seals & JGB take the stage at 8 p.m.

Saturday, it’s Dennis DeYoung, a founding member of Styx.

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. He is most revered for his powerful, high-spirited, Hammond B-3 organ, and keyboards in the Jerry Garcia Band.

Seals spun his B-3 magic with the 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, Seals serves up a tasty mix with a little R&B and gospel thrown in to spice things up.

Seals and JGB bring an intuitive, expressive style, soul, spontaneity and remarkable chops to the table. Their chemistry is the focus from which they create a spontaneous and high art where the sky is the limit musically.

They offer an exciting, often psychedelic musical journey that changes nightly and keeps the audience dancing and smiling.

In addition to the often-played staples, the band has been exploring the back catalog and performing lots of super rare tunes, some of which The Jerry Garcia Band played only a few times over all those years.

Adding his rock-gospel-soul-rhythm and blues touch with his funky style of playing, Garcia nicknamed him “Master of the Universe.”
