Jay OM (Journey / Omsphere / Crocodile Rangers / Star~Trip)  is the DJ name of, Milan born but now London based, Giampiero 'Jay' Mastino, label manager of Free-Spirit Records.

Jay forged his earliest psychedelic-rock influences playing guitar in local bars in Milan. His romance with the decks began in the late 80's whilst working for a local radio station where he was given the opportunity to spin his first record. This love firmly in place the move to London followed in 1998. Soon thereafter he started djing professionally as Jay OM and in 2003 he studied Sound Engineering and Music Technology and began a solo production project under the name Journey and another collaborative project called Star~Trip. Jay also began producing progressive under the name Omsphere in 2009 and has a further psychedelic collaborative project with Ralph K (Braincell/Solar Spectrum/Rastaliens) called Crocodile Rangers.

In 2004, Jay conceived the vision of a network of like-minded artists in the psy-trance, progressive and ambient genres, all working to promote themselves and each other under one banner. Thus the Free-Spirit label was born... originally intended to focus on artist management, the label's skyrocketing success combined with the enthusiasm of Jay, the artists and fans enabled Free-Spirit to outgrow its horizons.

Jay has compiled and released multiple successful compilation releases on Free-Spirit Records, including Brahamaputra (2006), Eupsychia (2007), Neophilia (2008), Mutual Reality (2010) and Phosphenes (2011).  As Journey he has released a solo EP in 2008, a solo album, The Man who Sold the Time, in January 2009, followed by a teaser EP, The Ripple Effect Part I, in July 2010 and has recently completed working on his second Journey album, Through the Mirror, to be released in September 2011 on Free-Spirit Records. As Omsphere he released his debut solo EP, Earthling, in November 2010 followed by a collaborative EP with Solar Spectrum, The Earthlings, in May 2011. As Crocodile Rangers he has released a track on the Free-Spirit compilation Phosphenes and is currently working on a debut EP.  Jay has also released numerous tracks on several other international labels under his various projects.

Today, Jay's reputation as an active, involved, and hard working individual in the global trance circuit precedes him. His commitment and enthusiasm for trance music has left an indelible impression on the world scene already and Jay's future has never looked brighter, from his burgeoningly successful record label to his organized events to his upcoming solo releases. Jay works tirelessly at his art and trade and the music he brings to the masses exemplifies the fruits of his labour and energy.
