“Tilt” Celebration of Light & Music on Summer Solstice (Grace Cathedral)

Submitted by the Event Organizer

TILT is a different angle on music, an intimate concert in celebration of light, taking place in the marvelous ambiance of Grace Cathedral on the longest day of the year.

We begin the evening with The Warm Up, a reception with summery spritzers and canapés accompanied by the exuberant fusion of global rhythms and soulful improvisation performed by internationally recognized Wobbly World.

As the sunlight fades from the glittering stained glass windows, revel in gorgeous songs of diverse genres performed by celebrated soloist Leah Crocetto and pianist and producer Ronny Michael Greenberg. Ronny’s virtuosic talents have graced the stages of esteemed venues across the globe, and Leah, whose voice blends finesse, depth, and emotional clarity, brings authenticity and brilliance to every stage she graces. The repertoire and the performance will be simply unmatched.

We’ll be bringing the sunset indoors courtesy of Mad Alchemy, a company that has been mesmerizing audiences with its Analog Liquid Light Show since 1971.

Event Details

What is TILT? The name TILT refers to the angle of the sun at the summer solstice, the point where the sun appears to reach its highest point in the sky for the year (the word “solstice” combines the Latin words sol for “sun” and sistere for “to stand still”).

TILT is in memory of Paul Crane Dorfman (1939-2018), a good friend of the cathedral who loved music, culture, houses of worship, fresh ideas, and mentoring young people.

About the Artists

Leah Crocetto

American soprano Leah Crocetto, praised by The New York Times for her “agile coloratura technique” and “full, penetrating sound,” is known for her commanding interpretations of opera’s most iconic heroines. A frequent presence on international stages, Crocetto recently returned to the Metropolitan Opera and Opera Australia as Aida, earning acclaim for her vocal warmth and emotional depth. She made a standout debut as Odabella in Attila at Teatro Petruzzelli and regularly appears in concert with leading orchestras, including the Chicago Symphony and Los Angeles Philharmonic under conductors Riccardo Muti and Gustavo Dudamel.

Her operatic roles span the Italian repertoire, from Leonora in Il trovatore and Desdemona in Otello to Mimì in La bohème, Suor Angelica, and Luisa Miller. She has performed with major companies including San Francisco Opera, Arena di Verona, Israeli Opera, Frankfurt Opera, and Opera Philadelphia. On the concert stage, Crocetto is a celebrated soloist, having performed Mahler’s Symphony No. 2 and No. 8, Beethoven’s Ninth, Verdi’s Requiem, and Pergolesi’s Stabat Mater. She is featured on Deutsche Grammophon’s Grammy-nominated recording of Mahler 8 with Dudamel and the LA Phil.

In addition to her operatic and orchestral work, Crocetto released the EP Momenti with pianist Ronny Michael Greenberg in 2023, showcasing genre-defying repertoire that highlights her expressive range. She currently works as a lecturer and voice professor in Vocal Arts at the Butler School of Music at the University of Texas at Austin, where she mentors emerging vocal artists.
With a voice that blends finesse, depth, and emotional clarity, Leah Crocetto continues to bring authenticity and brilliance to every stage she graces.
