Riccardo's career spans from opera to concert work as well. He has been a tenor soloist in Beethoven’s Ninth Symphony with the Etobicoke Philharmonic, in Haydn’s Lord Nelson Mass with ChoralWorks under the baton of Brian Rae, in Haydn's The Creation with Toronto Sinfonietta and the Oakham House Choir at Ryerson University, and in Dubois' The Seven Last Words of Christ with Choral St. Eustache in Québec. He has also toured in several U.S. cities with former I Sing Beijing whose mission was to recognize Mandarin as a lyrical musical language and introduce Chinese operatic repertoire to the mainstream opera world.

In competition, Riccardo was a Great Lakes Regional finalist at the prestigious Metropolitan Opera National Council Auditions. He was the recipient of the Opera Buffs award from the Metropolitan Opera of New York.

Riccardo’s career has extended overseas performing at various venues in Germany. The first one took place at Lindenfels castle in Lindenfels and followed by another in Boppard as part of the Mittelrhein Musik Festival under the helm of Helge Dorsch. That was followed by another concert soon after in Honolulu, Hawaii singing alongside mezzo soprano, Deanna Pauletto, and Hawaii native and baritone, Quinn Kelsey. This marked his début with the host company, Hawaii Opera Theater. He has had great success in reprising the role of Alfredo in La Traviata marking his debut with Miami Lyric Opera in February 2020.

He is currently a member of the Canadian Actors' Equity Association, ACTRA Toronto, and the American Federation of Musicians union in conjunction with the Toronto Musicians' Association, Local 149.
