In the early nineties Antonio Gabriele lived in Bologna and met many musicians and singers of the underground scene, in particular Hip Hop and Hard Core.

For the "Sangue Misto" he recorded a guitar solo in the song "la porra" from the album "SxM"; with Neffa he recorded "Il richiamo della cippa" in the "Etti Panetti" group in the album "Livello 57 - zona a rischio"; with Deda on drums, he played guitar in the Hard Core band "Globuli Rossi", with Roberto Di Egidio (ex Giulio Dorme) on bass and Paolo Azzurro on vocals. For a short time he played the guitar in the Hard Core band from Emilia "Paolino Paperino band", closing his Hard Core period.

In the same period (mid-nineties) in his hometown (Sannicandro Garganico - Foggia - Puglia) he founded the Progressive/Jazz Rock band "Effez" with which he recorded the self-produced CD "Dottor Hersellius".

Later he collaborated on various projects and composed many songs.
