Tech Watch

THE AUG. 30 Mann Skyline Stage show with Umphrey's McGee and Sound Tribe Sector 9 features a unique tech come-on.

Audiophiles in the audience can relish Umphrey's intricate, prog-rock jams exactly as the band and their sound engineer intended by renting a portable rig - wireless Sennheiser receiver and high-end Audio-Technica headphones - that tune in to the live soundboard mix.

Advance tickets go on sale tomorrow at $34.50 at manncenter.org.

Add $40 for sound-rig rental.
