Most recently, as soloist with the Philadelphia Orchestra at Avery Fisher Hall in New York, and during their tour to Beijing, China, under the baton of Marin Alsop, Thomas debuted Roydon Tse's Yellow Crane Tower, which prompted the review, "Tenor, Thomas Glenn was heroic in his narration of the tale."

In 2025, Thomas performed the high flying, Signor Adolpho Pirelli in Sweeney Todd at Utah Opera, which was reviewed as "zany" and "expertly sung". This year also brought two productions of Le nozze di figaro as Don Basilio/Don Curzio, at Utah Opera and at Palm Beach Opera, prompting the review, "Thomas Glenn was brilliant … He demonstrated agility on stage… along with a smooth and even tenor voice."
