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 a signature TILT cocktail, local craft ales, and bistro bites. 

As the sunlight fades from the glittering stained glass windows, revel in gorgeous songs of diverse genres curated by pianist and producer Ronny Michael Greenberg. His virtuosic talents have graced the stages of esteemed venues across the globe.  

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.
