This is what revivals were made for. Director Marisol Vega’s production of ‘Echoes of Yesterday,’ which opened last night at the Regent Theatre, doesn’t just recreate a classic score — it reinvents it with a raw, vibrant energy that feels like something entirely new.

Leading the charge is the incomparable Ana Luisa Sanchez as Elena, whose voice has that quality that great musical theater voices have: the technique fades away and you’re left with pure emotion. Her rendition of “Yesterday’s Echoes” in Act Two will leave you in tears — an experience only heightened by the stunning visual splendor all around her.

The production design by Gabriel Marquez is a marvel, creating a world where the past feels both nostalgic and urgent. The set transitions, which cleverly use projections to shift the audience between different time periods within scenes, are ingenious and keep the momentum flying through the two acts. Watch for the Act One finale — it’s a masterclass in how to integrate light and sound to create emotional depth.

But the first act is where things get murky. Marisol Vega’s staging feels like it wants to do too much at once. The opening number, an explosive reimagining of the classic “Waves of Memory,” might be visually dazzling, but it’s hard on the ear — the harmonies are lost in a maelstrom of sound and movement. It’s a puzzling choice by someone who nails the quieter moments so beautifully elsewhere.

Audience reactions varied wildly during the first act; some were engaged, some visibly restless, and a few seemed utterly confused. The second act was a different story — everyone was leaning forward, eyes wide, mouths open in awe at not just Luisa Sanchez’s performance but also at the ensemble’s breathtaking choreography that brought the house down.

The revival is strongest when it trusts its own material and allows the actors space to explore their characters on their terms. Vega should have let that happen more often in Act One — less directorial heavy-handedness, more of what the show has given her: a story worth telling with every note.

So why am I giving this production four stars? Because even if the first act is a bit of a bumpy ride, it’s impossible not to be swept away by the magic that happens in Act Two. It’s the kind of theater that reminds you why people keep coming back — the emotional wallop and artistry are just too potent.

Look, you should see ‘Echoes of Yesterday.’ You should experience this revival because of how it reinvigorates the classic material with a modern touch without losing its heart. Get there before word spreads wider and tickets get harder to come by. The show might still be finding its footing in Act One, but Act Two is worth the wait — and then some. Estamos aquí.
