The Tommy Caggiani Therion Project, described by the leader as "Emotional Perceptive Music Experience for the Soul", is the fruit of his travels and experiences, dispalying his attitude towards life. The repertoire, based on original compositions, blends ethnic rhythms and jazz improvisation with high emotional power seeds. The name of the group is inspired by the Greek word therion, a creature half animal and half man, and by the energy alluding to the therianthropes found drawn on walls in prehistoric caves. Like the superhuman strength from the transformation in therianthropes is palpable, thus the energy of the music created by the group can be compared to the energy required for the transformation of the human being. A similar energy is transmitted with the music of the sextet, to make vibrate and dream through the emotion. Like musical shamans to the listener, they are sowing World-jazz musical seeds, expressly composed to paint everyday's chiaroscuro with the colors of the melodies.

The group recorded their first album The Energy of Transformation in 2014, released by the Basque label ERRABAL Jazz. In November 2015 they recorded their 2nd CD Magic Seeds released in June 2017 by Hevhetia. A double live album, Live in Krakow has been also recorded during the Jazz Juniors Festival 2015, and will be edited this year.

Drummer, percussionist, composer, music therapist and mathematician Tommy Caggiani is an exception in the world of jazz. A born Italian who has been living in many different parts on the planet, like South America, the United States and recently in various places in Spain, he has soaked up different musical cultures shaping his music as he is: eclectic, heterogeneous, rich in rhythms and sonorities, generous, optimistic, energetic and happy; a form of playing that celebrates life. A life which has led him to collaborate with wonderful artists such as Edoardo Bignozzi, Maurizio Giammarco, Antonello Salis, Donald Alridge, Malik Yaqub, Bob Sands, Jerry González, Jorge Pardo, José Luis Gutiérrez, Javier Colina, Kepa Junkera, Baldo Martínez, John Williams, Alex Weiss, Claudio Recabarren, Ara Malikian and Javier Paxariño, among others. He has recorded more than 30 CDs with Italian and Spanish groups.

Tommy Caggiani, beside being a jazz and world music musician is also a drums teacher and tutor of non-western traditional membranophones (percussion and history of the ethnic percussion) at the Superior Jazz Conservatory of Navarre (Spain). Being also a trained music therapist (Master at the Danish University of Aalborg), he has conducted research on self-healing therapies related with sound and ethnic music, creating his own method of "Healing Percussion".
