For the past two years, Unknown Mortal Orchestra member has released an 'SB' single topping off the end of the calendar year. Following 'SB-01' and 'SB-02' from 2013 and '14, band member Ruban Nielson and his brother Kody have returned with the psychedelic rip 'SB-03'.

Ruban's wife Jenny created the album artwork seen above for the jumping instrumental piece, which stretches over the course of 12 minutes. It's a nice way to top off what was a joyous year for the crafty rock outfit.

Listen to 'SB-03' below.
