Barrie "Barriemore" Barlow (born 10 September 1949, Birmingham) is an English musician, best known as the drummer and percussionist for the rock band Jethro Tull, from May 1971 to June 1980.
Christened Barrie, the 'Barriemore' was an affectation to suit the eccentric image of Jethro Tull (much as Jeffrey Hammond had become "Jeffrey Hammond-Hammond").
Barlow was a former bandmate of Jethro Tull frontman Ian Anderson. He joined after the departure of Clive Bunker, in 1971. Barlow played on the EP "Life's a Long Song", before embarking on a concert tour with the band. By this time, the original members of The Blades were now back together with the addition of Martin Barre, and a relatively long-running edition of the Jethro Tull lineup was to follow (late 1971–1975).
Barlow's first gig with Tull involved an unfortunate episode in Denver, Colorado when the local police tear-gassed the audience from helicopters, both outside and inside the Red Rocks Amphitheatre. Believing that they would be arrested, the band made a run for it after the show in an unmarked station wagon where, hidden under a blanket on the floor in the back, Barrie was heard to ask Ian, "Will it be like this every night?" Anderson replied, "As a general rule, only on Tuesdays and Thursdays."
Upset by the death of bassist John Glascock, with whom he had become very close, Barlow left Jethro Tull in 1980 after completing the final leg of the Stormwatch tour.
Barlow went on to do various session projects, including work with Robert Plant, John Miles, and Jimmy Page, and he also started his own band for a spell called Storm. He played on the Yngwie Malmsteen album Rising Force. He played on the Kerry Livgren album, Seeds of Change.
Barlow has a recording studio, The Doghouse, on his property in Shiplake, Oxfordshire, England. He is currently managing a band from Henley on Thames called The Repertoires, and has also been linked with other local bands which echo his own folk-influenced musical history, such as Reading's Smokey Bastard.
Barlow played percussion on "Artrocker", the opening track of the critically acclaimed 2006 album Get Your Mood On by London indie punk band, Dustin's Bar Mitzvah.
In an interview in the December 2007 issue of Drumhead magazine, Barlow announced that he is looking to play on the road again.
