The Stravinsky Auditorium in Montreux was filled with the energy and rhythm of Trombone Shorty on Wednesday night, who managed to captivate the audience with 70 minutes of funky vibes and blazing virtuosity, followed by Usher's performance.

"His energy was incredible, especially how he connects with the audience, how he transmits it," Aloise, a young woman who, like many others, was enthralled by the trombonist from New Orleans, who's real name is Troy Andrews.

Shorty first came on stage with his trombone in one hand and trumpet in the other, and from the first minute he moved the audience with an incessant swell of rhythm and crescendo, seemingly without taking a single breath.

Not only did Shortly show his extraordinary skills with the instruments he masters from the beginning, but he also carried the tune with his voice, holding notes for surprising length or dueling with two of his colleagues, who played tenor sax and bass sax.

He also paid tribute to one of James Brown's songs, played with hip-hop rhythm without ever leaving his funky tune, and bade farewell to Montreux saying "I will return." However, he did not return to join the subsequent concert by Usher and The Root.

The Rythm and Blues star of the last two decades and one of the best-selling artists in the last decades, Usher did not have to try too hard to conquer the audience - who had been very thrilled already - with his greatest hits such as "Yeah," "Bad Girl," and "Let It Burn."

The audience left the hall contented after enjoying two artists who began their carriers years ago but still manage to show that they will remain excellent musicians for many years to come.
