Ok, warning.. Before you even open this track, notice that it is an entire hour long.
So if your spouse, significant other, neighbors, or your dog that is waiting to get fed come looking for me, I'm just going to shrug and tell them "Not my fault, I did a disclaimer.."
If you are not the sort of person who jams to backing tracks, this track probably will seem pointless. "Who would want to do that? It isn't even an actual song or anything. Hmph. "
But if you like to improvise over long easy grooves.. I apologize in advance, but your life may start to disappear an hour at a time. Not my fault, I gave a disclaimer! So blame it on alien abduction or something when people start asking where the heck you've been.
So the track is an easy slow groove in A minor with a little bit of funk to it. It isn't exactly the same chord progression for the whole hour. It goes through a fair number of typical chord progressions in A minor. While it doesn't stop or make an obvious break between them, the current one being used it displayed for those folks who may find that helpful.
What can you get out of it? Well, lots of stuff, depending on what you put into it. You can work on intonation, holding the groove over little variations by the other instruments, getting a scale down real thoroughly.. But if you do improvisation, you can work up some new riffs while exploring the key and feel, try the riffs in different contexts to get a good idea where they might fit in actual playing situations. You can try out different scales or modes to explore how they lend their distinctive flavour to music. If you write at all, it is not unlikely that you may come up with some melody ideas for your next song/piece. You can try doing the riffs/phrases/bits you come up with with different timings or techniques. If you play electric, you can test out effects and settings to get more of an idea how they really work when playing.
A long track that is not some particular song can be good to work with, since it is more "neutral" in that you don't have a set idea of what it "should" sound like, so you can explore your own ideas a bit more creatively.
Anyway, like I said, this is definitely not going to be for everyone.
The creator of the track couldn't resist jamming out on his guitar for a brief moment at the beginning. Can't say as I blame him. And it is actually kinda nice, since it gives you about 30 seconds or so to pick up your instrument, listen and get ready to play.
For the brave jammers, improvisors and composers.. I wish you good playing.
