Holy shit, Budo. You've just produced one of the best London Grammar remixes ever, infinitely better than the original. Seriously, my eardrums are melting right now -- this being the 5th listen.
The original version of "If You Wait" features on London Grammar's recently released debut album by the same title (If You Wait). It's a sparse and gentle single, with fluttering string work and a heavy focus on Hannah Reid's vocals.
This rendition by Budo still keeps things relatively mellow, but integrates a million extra layers -- my favorite being the higher pitched vocals. If you dig it, be sure to grab a free download here.
