Next Thursday prepare yourself to be blown away with some ultra groove when Unknown Mortal Orchestra takes over the Astor Theatre. The Portland via New Zealand outfit is fronted by psychedelic visionary Ruban Nielson, and they're returning to Australia for a national tour this December.

It's been quite a while since Australia last saw the power of UMO, and it's about time they came back to give us another taste. Nielson and his cohorts from his adopted hometown - bassist Jacob Portrait, drummer Riley Geare, and keyboardist Quincy McCrary - will play at Perth's Astor Theatre on Thursday December 3 as part of a national tour marking UMO's first shows since their exclusive dates at the St Jerome's Laneway Festival in 2014.

Their new album Multi-Love (released in May) has been absolutely smashing it - working its way among the best of this year's albums! It follows the introspective and road-weary II (2013) and their self-titled 2011 debut. If you haven't heard the story behind UMO, they started as a bedroom project when Nielson relocated to Portland and dissolved the Mint Chicks. UMO's 2011 self-titled debut blew the lid off their small operation and rocketed them into speakers around the world.

We told you to be prepared to be blown away - though conceived in the bedroom, UMO are a force to be reckoned with on stage. With Geare and Portrait locking down a tight groove, Nielson's guitar prowess really comes to the fore. The band's songs often descend into extended psychedelic jams, and with the addition of McCrary on keys, their new material - as well as favourites from their first two records - has taken on an extra dimension live. Don't miss them when they play songs from Multi-Love in Australia for the very first time!
