Last Sunday we had a concert with a new formation of Tetra Pack. Interesting new sounds with bass guitar and drum kit of Pau. The sound of trombone was also something new, like some new effects that I tried that night, At some points we were very aggressive, but the list of tunes put some breaks and made a very dynamic concert. Highest pick was the performance of our guest Sandra. Very nice and gentle on first tune and energetic on the second with crazy improvisation that pushed the band a lot. Next concert we will play in trio. Hope to hear something new.
