“Under Skies” is one of many "dorm room” songs made to, one of many girls (at least a few).
Living in a small apartment, usually means: thin walls. As a result; plenty of acoustic mellow songs have been made, and tailored to fit in these particular environments.
Spending the evening hours with an acoustic guitar, (typically after rehearsing electric with the band), feels like a different kind of craft and is quite refreshing. Anyway, it's just one of those things that I've been doing all my life.
Though many of these songs have a quiet, warm nature, many of them also contains a lot of strange guitar stuff, as these songs often were composed by just playing or toying around. Daydreaming with what you've got in front of you.
Some of them are quite long too, on this particular piece, I removed about two minutes of instrumental guitar play, to maintain some kind of focus.
