Twenty years of activity and advancement is heard in this fourth album from the dynamic tuba power trio of tubist Sergio Carolino, guitarist Mario Delgado & drummer Alexandre Frazao, an electric jazz unit of deep power and drive, on this album leaving behind cover tunes that included Deep Purple and Thelonious Monk to focus on compositions from each band member.

Guitarist Mario Delgado leads this 2002 session of lyrical modern jazz merging a diverse set of styles including traditional jazz, blues, and country-western, with an experimental edge and free jazz inclinations, in a quintet with Alexandre Frazao on drums, Andrzej Olejniczak on tenor saxophone, Carlos Barretto on bass and Claus Nymark on trombone.

Lokomotive's "Labyrinths" with bassist Baretto at the top of his game in playing and scoring this driving and unorthodox set of pieces, performed with two of Portugal's most in-demand players.
