Yellow Jacket Metropolis

A typical nest consists of two or three thousand workers and one queen. With these large nests, we may have as many as 100,000 workers. (…)

Rather than starting spring with a single queen – as yellow jackets traditionally do – these nests are starting with possibly a couple of thousand workers and possibly multiple queens.

We’re not really sure how this (…) works. It could be that the daughters of the original queen don’t leave the nest or that the queens have developed some way to cooperate.

Giant Steps

Animations visualizing John Coltrane’s “Giant Steps”. One by Michal Levy that takes an artistic approach, and another by Iain Houston that breaks down the song’s signature ditone and quadratone chord progressions.

Summery

As summer fades to autumn, hot jams congeal into warm grooves and Centripetal Notion serves up an hour-long mix of semi-retrospective summer tunes before the weather turns south.

This is also the beginning of what will be an increasing amount of collaboration here on CN – the tracklist was curated by my good friend and hip-hop/R&B jive monkey, Mitchell Killman. If you dig this, leave your thoughts and check out his Last.fm profile.

As always, you can get this and more downloaded automagically to your iPod or iTunes by subscribing to the podcast.

More info on future centripetal symbiosis is forthcoming.
