The international Record Store Day happens Saturday, April 18.

And as usual, Record Stop in Patchogue is planning a block party of sorts to mark the occasion.

For the uninitiated, Record Store Day involves special release records available for the first time only that-day, as well as discounts and other promotions from independent record stores. And plenty of music and partying.

Lines are known to form around blocks for music fans clamoring for that long-awaited album finally pressed or re-released in vinyl form.

“One of my favorite days of the year is Record Store Day, which happens the third Saturday of every April. And we are blessed to have one of the greatest record stores on Long Island right here in our hometown,” said David Kennedy, a vinyl enthusiast and the executive director of the Greater Patchogue Chamber of Commerce.

The festivities in Patchogue run from noon to 5 p.m. that Saturday on Railroad Avenue, where Record Stop is located. The street will be closed to vehicular traffic during that time, from West Main Street to South Street.

The Patchogue Village Board approved the road closures at its Feb. 24 meeting.

Record Stop will be hosting live music and serving craft beer — with help from neighboring Patchogue Beer Project, also on Railroad Avenue, according to owner Jeff Berg.
