T. Parlo was used as writer credit for the track Natale on the compilation Il Grande Viaggio Di Gigi D'Agostino Vol. 1.
Natale is a cover version of X-Mas In Freiburg by Christian Morgenstern.

At the time of the release year of the cover version (2001), Gigi D'Agostino did not know the name of the composer of Natale, so he credited him as T. Parlo.
In the Italian pronunciation T. Parlo sounds like ti parlo which means I speak to you (as a call to the composer).
