March 31 was the International Transgender Day of Visibility, and though the new documentary from Shout! Studios, “The Sound of Identity,” didn’t drop on that day, it’ll arrive just in time for Pride month. The film profiles transgender opera singer Lucia Lucas and her historic 2018 performance at the Tulsa Opera, where she was the first trans woman to take on a principal role in opera history. This was nothing less than a career-defining risk, but Lucas collaborated with composer and mentor Tobias Picker to bring her acclaimed baritone voice to the role of Don Giovanni in Mozart’s opera of the same name. The film, directed by James Kicklighter (“Angel of Anywhere”), won the 2020 OUTshine Film Festival Programmers Award of Excellence for its thoughtful exploration of voice, gender, and performance. Don’t miss it when it begins streaming on June 1.
