Grillo.....has a strong, upbeat voice with an edge of cockiness in it that allows him to put a personal touch on these tunes made famous by other singers. Although Grillo's voice is unique, his presentation draws comparison to any number of predecessors such as Buddy Greco, Bobby Darin, and of course Sinatra. The assured phrasing, slight alteration of lyrics, and forcefulness of style allow Grillo to join that fraternity of singers who use their take-charge attitude to win over an audience.
Grillo delivers a vocal punch to match the blasts of the brass section. Grillo is an entertainer who can get a crowd into the performance through his personality and delivery.
