In 2017, having played the Slovenian  circuit for two years, the band put out 'Tja in spet nazaj' - 'There and  Back Again', a conceptual album dealing with the issues of what is  home, a wreath of impressions derived from personal experience of life  in migration. The album received positive response in the  media and with the general public. With the album's positive reception the  band's public presence needed to be developed, at which point Matjaž opted to  focus on classical composing and relegated his place in the spotlight.

In the winter of 2017, Janez Moder became the band's full time bassist. He is the original and  current member of one of Slovenia's most progressive bands Moonlight  Sky as well as an extremely active session and live musician who's  played with Gal in Galeristi, Aritmija, Didiwa, Alkimia and has  collaborated with the likes of Severa Gjurin, Goran Bojčevski, Marko  Hatlak, to name but a few.
 

The band took to  Slovenian stages, media outposts, and radio studios to present the  album nationwide, accumulating interest with the public. The hit song 'Never be the same'  (Nič ne bo kot je bilo) gained traction on radio stations (Val 202, Slovenia SI, Radio BOB...).
 

In  November of 2018 the band was officially joined by academic violinist  Ana Mezgec, who had previously appeared as a guest violinist, blowing the  audience away with her energetic and perfected playing style along with a  confident yet understated stage presence.
 

With two new  last names added to the roster of band members, the old name "Jarc Gregorin Trio"  no longer fit the four-piece. The band decided to slowly phase in a new designation: "JG3O". At first the two  names would be used side by side making JG3O the largest trio around;  the name is set to change with new songs and the publication of the  second full album.
