Here's what Modern Drummer magazine had to say about it:
Even if you've heard Harrison blasting bullets with Porcupine Tree or King Crimson, those gigs won't prepare you for the rhythmic impossibilities Harrison delivers in his collaboration with guitarist/singer O5Ric on their debut recording, "Drop". Harrison's popular books Rhythmic Illusions and Rhythmic Perspectives and his DVDs Rhythmic Visions and Rhythmic Horizons explain his concepts in mind-blowing detail, but "Drop" is the soul of the drummer, plain and not so simple.
With every drummer of note, you can point to a record where he truly arrived. Where he owns it. It might not be that drummer's most popular recording, but it's the one where he innovated techniques that literally put him on the map. Steve Gadd = Steely Dan's "Aja". Tony Williams = Miles Davis's "Four And More". Dave Weckl = Bill Connors' "Step It". Vinnie Colaiuta = Frank Zappa's "Joe's Garage". Philly Joe Jones = Miles Davis's "Milestones". "Drop" is the record where Gavin Harrison's well-earned technical skills and good-foot grooves become one, as he dances through polyrhythmic madness, odd-metered overkill, and illusions realized with both mind and body.
All the songs were written and performed by Ric and myself and feature contributions from
