Mickey Hart Band at Blue Point Brewing Co.

There was a time, back about 20 years ago, when the rock group Grateful Dead would often roll into Long Island with a massive caravan during their many musical tours. Our area was always a dedicated stop, and their shows would bring thousands to Nassau Coliseum, filling the parking lot and providing the band’s many local devoted fans another regular chance to hear their trippy, long-form and jazzlike style of rock n’ roll…

But these days, with lead singer and guitar player Jerry Garcia long gone, the rest of the band has splintered, leaving the truly dedicated supporters (known as “Deadheads”) to sit and wait as remaining members of the ‘Dead will occasionally come to play stages at smaller venues around Nassau and Suffolk counties. Luckily for them, it just so happens that Saturday, Aug. 20, is one of those very dates, as one of the group’s two main drummers Mickey Hart is set to perform at the Blue Point Brewing Company in Patchogue for its 13th anniversary celebration.

A famous and frequent member of the ‘Dead, Hart will headline the event, will the bill also including a set from the trio of Michael Glabicki, Preach Freedom and Colter Harper (of the extremely popular jam-rock act Rusted Root) -- as well as a session from band Jam Stampede. As for Hart and his traveling crew, this is their only scheduled Long Island appearance, so getting tickets as soon as possible would probably be a wise plan. Purchases can be made online (through bluepointbrewing.com) for $39 or $45 on the day of the performance (and it’s a good bet there won’t be many of those left to buy).

Doors open at 1 p.m., with lots of arts, crafts, food and beer available during the day. Naturally, those partaking of the ales, drafts and other alcoholic beverages must be 21 and over -- but parents can definitely bring the kids to this all-ages event, with children 10 and under allowed in for free.
