Nestled between the instantly legendary festival in 1969 and the violence of the 1999 incarnation, Woodstock 1994 — a 25th anniversary celebration of the original — can be easy to overlook.

That installment, in Saugerties, N.Y., was supposed to be a slightly more grown-up (or, depending who you ask, commercial) version. But, as in 1969, attendees saw severe traffic jams, fences that could not contain the crowd and rainy weather that turned the festival grounds into a muddy slog.

Then, five years later, fires, rioting and reports of sexual assault at the 1999 festival made national headlines, and gave “Woodstock” a whole new meaning.

Now, for the 30th anniversary of ’94, a photography exhibition places the middle child of the festivals at center stage. The show, at the Opus 40 gallery in Saugerties, opens on Friday and runs for three weeks. It features work from Albert Watson, Henry Diltz, Cheryl Dunn and Danny Clinch, who remember the festival as messy yet rewarding.

That the show is taking place at all is thanks to Watson, who is known for black-and-white portraits of luminaries including Steve Jobs. The show was put together by Tyler Harte, a Manhattan property manager who moonlights as an organizer of concerts and skateboard events — and manages the building where Watson’s photography studio is. Harte realized that the anniversary was coming up and contacted Watson about potentially doing something with his 1994 photography, resulting in the show that Harte co-curated with China Jorrin, the Opus 40 gallery director.
