Just came across this clip of Luna with Justin playing Friendly Advice in their rehearsal space in LA in 2015.

The video was made by Britta and originally shared as part of the band's Pledgemusic campaign for A Sentimental Education, but I've taken it upon myself to let it out of Pledgemusic gaol as it's a shame for it not to reach a wider audience... hopefully the band won't mind!
