Making its third Denver appearance this year, Up Until Now, the livetronic offspring of Jay Murphy, is returning for Euphonic Conceptions' semi-annual Sonic Blossom festival, with support from Jay's brother David Murphy of Sound Tribe Sector 9 and Jon "The Barber" Gutwillig of the Disco Biscuits. Blending reggae, electronic, hip-hop and other worldly genres, Up Until Now delivers a show that can go in any direction — and with the addition of Murph and Barber's heavy musical muscle, this performance should be dripping with live jamming.
