Gavin Harrison of Porcupine Tree is recognized by those in the know as one of the world's premier drummers. He is the author of a couple of instructional drum books and won the Modern Drummer
magazine readers' poll for "best progressive drummer of the year" consecutively in 2007, 2008 and 2009. At around the 10:30 mark on this song, Harrison shows his skills when he takes the song's recurrent beat and flips it around so it almost sounds like he's playing it backwards. In an interview with examiner.com
, he was asked if this was something he just thought of doing on the fly. Harrison replied: "Well, I always think like that. I actually wrote a book in the late 1980s called Rhythmic Illusions
, which is about literally creating illusions with percussion rhythms – the way it sounds like you're playing backwards, or when you're messing around with the perception of where the "1" is, or making it sound like you're playing a different tempo even though you're not playing a different tempo.
There are all sorts of clever tricks you can do with rhythm if you truly understand people's common perception of rhythm. If you understand what people are expecting, then you can mess around with that and that's when you can create some really rhythmical illusions."
