Xander - that might be it - they are combining two different genres on this album perhaps and could be a reference to that - I can't wait to see what they explain it as - but acoustic meets electronica is not a bad guess. Nice - keep it going, it's fun to read all the different thoughts out there.
nice ideaJust my two cents...
could it be something as simple as:
Mylo - scottish electronica artist/producer, suggesting the influence/use of electronic beats/tunes
Xylo - suggesting the acoustic side of things (also present on the album)
-to - also? (I realize it is missing the second 'o' to mean "also") ultimately meaning Electronic and Acoustic Too...
Most likely a fool's search on google came of this but it makes since as well...the guys did in fact say that there was a massive clusterf*ck of acoustic songs and non-acoustic forces pulling at each other on this album.
