Take Five with Joe Morello

Not long ago I posted a clip of a drum solo by the great Joe Morello which has proved to be extremely popular. Since a meeting I thought I had this afternoon has been cancelled I’ve decided to take five minutes out to post another terrific drum solo.

The tune Take Five, composed by alto saxophonist Paul Desmond and recorded by the Dave Brubeck Quartet in 1959, became a hit at the second attempt when it was re-released in 1961. It proved so popular that the band performed many versions of it live, manu of which can be found on youtube. This one is not unusual in that it is performed at a faster tempo than the version that was released as a single. I read an interesting blog post a while ago that explains how Joe Morello’s arrival almost broke up the Dave Brubeck Quartet, as Paul Desmond and he had clashing personalities. I think Part of that was Morello’s predilection for tempos that were a bit faster than Desmond was comfortable with; Paul Desmond had a beautiful tone, but in contrast to many of his Jazz contemporaries on the instrument, he was never a speed merchant on alto saxophone. He seems to be less fluent than usual on this track, at least at first, probably because of the speed.

Joe Morello’s drum solo, on the other hand, is characteristically wonderful. Just watch his superb left-hand technique, from a relatively gentle opening to when he turns down the strainer on the snare drum he starts to build up to a stunning climax in which his hands are far too fast for the camera. It’s a great solo, not only because of it’s technical brilliance but because it’s so beautifully constructed. All in 5/4 time too…

Cosmology at a Crossroads – Poll

A short comment piece by Wendy Freedman has appeared in Nature Astronomy; there’s a free version on the arXiv here. It gives a nice perspective on the current debate about the value of the Hubble constant from the point of view of an expert on cosmological distance scale measurements.

The abstract is here:

We are at an interesting juncture in cosmology. With new methods and technology, the accuracy in measurement of the Hubble constant has vastly improved, but a recent tension has arisen that is either signaling new physics or as-yet unrecognized uncertainties.

For the record, I’d go for `as-yet unrecognized uncertainties’, primarily because this field has a long history of drastically underestimated error-bars!

However, the publication of this piece gives me the excuse to resurrect the following poll, in which I invite you to participate:
