Speaking of which, there’s always Pink Lady Lemonade by Acid Mothers Temple and the Melting Paraiso UFO (http://youtu.be/CcQTSEWbGyI). Depending on the performance, it ranges from 45 minutes to somewhere above an hour.
And then, of course, there’s always Earth and SunnO))), but playing those bands at proper volumes wouldn’t exactly be conducive to writing.
and just maybe, the Human League was at the forefront of electronic dance music of the early 80’s and produced a great album of pretty much instrumental remixes of some of their hits. Very much “of its time” but I like it.
I listen to a lot of instrumental rock at work, and for non-distracting but stimulating music, surf rock fills the bill. There are plenty of different styles, from mystical/floating (i.e. the Mermen) to hanging out at the beach club (the Aqua Velvets) to stomping a rival biker outfit (Satan’s Pilgrims). The surf genre is about 99% instrumental.
Second this. Apocalyptica are brilliant. I love their Metallica covers.
Kronos Quartet. Don’t let the fact that their Requiem For A Dream soundtrack is wildly overplayed stop you from checking them out.
The Books. I’m not sure how to classify them, but then, I don’t think anyone is. The safest genre to use is Experimental. A lot of their songs have words, but they’re vocal samples instead of lyrics.
Well then, for my own instrumental chill out mix, I might recommend the following artists:
Bonabo
Daft Punk
Deadmou5
DJ Shadow
Gorillaz (still has lyrics)
Johann Johannsson
Massive Attack
Moby
Orbital
Sasha + John Digweed
Thievery Corporation
Zero 7
Rodrigo y Gabriela also do a great cover of the Metallica instrumental Orion.
“The Duel” from Electric Dreams (which is actually Minuet in G major by Bach)
Chilli Hot from the Get Shorty Soundtrack (not sure of the one I link to is the official version)
Possibly my favorite piece of music period: Dream Academy’s Please Please Let Me Get What I Want (AKA That Music from Ferris Bueller in the Art Museum.)
Also:
DJ Tiesto
Paul Oakenfold (although some of his songs are lyrical)
Paul Van Dyk
David Holmes (sort of a trip hop / acid jazz sound. Did most of the Ocean’s Eleven soundtrack).
