I warmed up with Rick Dior's hand warmup exercise on the practice pad.  
I did some work on my shuffle bass drum patterns on the drum kit. Progress was noted. 
I worked through 3 snare drum etudes listening carefully for evenness within my 7 and 9 stroke rolls and the lightness of my tap strokes. They sounded nice.  
I recorded with a heavy metal drum play along. On the playback I noticed that my time was drifting ever so slightly. I addressed that shortcoming by turning up the backing track on the next recording. That helped. 
I finished up this short practice playing along with Trane's Blues from Miles Davis' "Workin' album." I paid close attention to the intensity of the ride cymbal work.

40 minutes.
