Michigan tenor Joseph Leppek made a strong impression as Pedrillo – who with his lover, Blonde, was captured along with Konstanze. Leppek brought energy and vocal power to the martial aria Frisch Zum Kampfe in which Pedrillo summons his courage. He displayed lyric beauty in his guitar-accompanied serenade In Mohrenland gefangen war, and comic mastery in Pedrillo’s rambunctious duet Vivat Bacchus! Bacchus liebe! with the tipsy Osmin.

I have admired Leppek’s appearances at the Glimmerglass Festival and the Central City (Colorado) Opera. Notably, he sang the lead role of Tony in Bernstein’s best-loved musical [Review – Glimmerglass Festival’s Dazzling “West Side Story”: Youthful Artistry, Theatrical Authenticity, July 19, 2018. Leppek’s Pedrillo showed that, in addition to his being persuasive in the romantic role of Tony, he excels in a comic tenor role as well.

At the outset of the second half, Pedrillo sings his courage-summoning aria “Frisch zum Kampfe” perched so high above the stage that one feels he has every reason to be terrified. Still managing to strike a comic mood, Joseph sings with clarity and enormous charm.

Tenor Joseph Leppeck, LOKC resident artist, gave the role a clear timbre and cheeky enthusiasm. Playing off each other, Boehler and Leppek carry most of the comedy.

The performances are well done all around. Leppek’s Pedrillo is comic without being overbearing.

Saturday night saw the continuance of the KC Lyric Opera’s “Explorations” series with “Mack the Knife is The Man I Love”, a musical entertainment featuring the music of the Gershwins & Kurt Weill. The Lyric elected to use the evening to favor us with the talents of some of their up-and-coming resident artists to overall very pleasant effect....And just how this reviewer got along so far without hearing The Man I Love in a male voice she’ll never know. But the fact is, Joseph Leppek’s tenor renders a positive melter of the old classic.

As star-crossed lovers, soprano Vanessa Becerra and tenor Joseph Leppek had wonderful chemistry. [...] Singing the role of Tony demands an otherworldly vocal range, which Leppek ably delivered, assisted by a capable falsetto. His rendition of “Something’s Coming” was a tour de force. Like Becerra, Leppek is also a trained opera singer but pulled his vibrato to sound less operatic for this role, which made him earnest and believable.

“All the leads were excellent, with Joseph Leppek’s Tony capturing both the ardor and the fragility of his doomed love for Maria, Vanessa Becerra.”

—Opera Wire

Vanessa Becerra was a vibrant, touching Maria; Joseph Leppek, a pretty-voiced Tony. Amanda Castro’s dancing brought an electric energy to Anita; Corey Bourbonniere was a tough Bernardo [...] The big ensemble of Glimmerglass Young Artists made a strong showing in the dances, which are the pulse of the show. Glimmerglass does musicals with full orchestra and no amplification, which makes for a less slick aural experience than one gets in a Broadway theater, but the resulting authenticity is preferable.

The spry cast, led by Joseph Leppek, as Tony, and Vanessa Becerra, as Maria, gamely navigate Bernstein’s tri-tonal score.

As Tony, Young Artist Joseph Leppek grew in stature throughout the performance, from a somewhat thin-voiced “Something’s Coming” to a warm, full-throated “Maria,” exhibiting both delicacy and power in his final moments. Both Leppek and Becerra projected pure innocence in the imagined wedding scene, “One Hand, One Heart” and their love story was believable and touching.

Still, this was a talented cast, and their youth was an asset across the board. [...] As Tony, tenor Joseph Leppek sang elegantly, danced gracefully, and had a winning chemistry with Becerra.
— Classical Voice North America
Both Joseph Leppek as Tony and Vanessa Becerra as Maria, the doomed lead lovers from rival gangs, exhibit strong, expressive voices as well as dramatic chops. In their solos and duets, they are fully convincing as passionate youngsters falling into the first throes of romance.

As Manhattan’s star-crossed lovers, Texas soprano Vanessa Becerra and Michigan tenor Joseph Leppek were dramatically convincing. Both were youthful in appearance and and both possessed appealing lyric voices that blended beautifully for the classic duets Tonight and One Hand, One Heart. [...] Leppek, a 2018 Glimmerglass Young Artist, proved to be an engaging actor and leggiero tenor, possessing a beautiful head-tone for Tony’s high notes. I had seen Leppek previously in smaller roles in Donizetti’s “The Siege of Calais” at the Glimmerglass Festival and the world premiere of Heggie’s “It’s a Wonderful Life” at the Houston Grand Opera. His success as Glimmerglass’ Tony – the lead male lead role in an important production of a major American musical – brings to mind a variety of tenor “youth” roles in opera and musical comedy (such as Piquillo in Offenbach’s “La Périchole”) for which he should be an ideal choice.

The six men sang their hearts to the edge of fear. They were the six burghers of Calais, offering their lives to a King so that the other citizens of their city could be spared. The heroism of the burghers turns the dramatic wheel in Gaetano Donizetti’s opera. [...] The burghers, a magnificent ensemble of Chaz’men Williams Ali, Adrian Timpau, Aleks Romano, Carl DuPont, Makoto Winkler and Joseph Leppek, pour forth every shade of emotion, thanks to the astute and knowing direction of Francesca Zambello, the Artistic and General Director of Glimmerglass, who also keeps them moving fluidly around and among each other even on a somewhat crowded stage

This staging, performed enthusiastically by members of the Aspen Opera Theater Center, and directed briskly by Edward Berkeley, served as a rewarding vehicle for the wigged Big Three. Vautour’s Mozart teamed nicely with tenor Joseph Leppek, who did his best with Haydn’s minimal involvement, and basso Andrew Munn, suitably gruff as Beethoven. The trio displayed fine singing and decent acting, each doubling in smaller roles along with the rest of the cast.
