A few years back I had the pleasure of attending a drum clinic given by the great Dennis Chambers. One of the things he talked about was how you can make something your own by mastering & then varying something that someone you admire had done. By way of demonstration he played Jeff Porcaro's beat for Rosanna, followed by his own version of the beat, which he'd come up with when he sat in on that song one night at a Toto concert in, of all places, Vienna.
Here Jeff reveals how he came up with a beat that has entered the drumming canon. To paraphrase a composer I admire, "Different buildings, same stones."
