As of 2014, Jones is performing in the U.S. with Boston-based guitarist Frank M Evans, as Trans-Portal, expressing many of the Quintessence songs in a more intimate and acoustic format.

In 2010, Maha Dev's new Quintessence were invited by Michael Eavis to play the 40th Anniversary Glastonbury Festival, where they were joined by original vocalist Jones.
