There's an argument, and it's one I'd support, that jazz has always been "world music".
It might not be the authentic, centuries-old folk music that has grown out of the tribal and nomadic cultures of the past and been passed from mother to son, father to daughter, and that is now marketed under that label of convenience.
But, from its sources in Africa and the American south and all the way through - from Dizzy's fascination with Cuba to John McLaughlin's delight in India - jazz has always incorporated world influences.
Today the margins between conventional musical styles are even more blurred and, a lot of the time, even more exciting. And if you don't believe me, here are some gigs that could turn you around.
First stop is the open-air Arena at the mac in Cannon Hill Park, for a Sounds in the Round performance by Susheela Raman.
No, she's not a jazz singer, but it has been said that she sounds like Billie Holiday might if she had been born into a traditional Tamil household, and she will loosen your ears for what is to come later in the weekend.
Born in London in the early 1970s to South Indian parents, Raman's music owes as much to jazz, blues and funk as it does to her own heritage of classical Indian music.
A full, soulful voice and music which operates between the experimental contemporary classical/jazz of Talvin Singh or Nitin Sawney and the harder beats of the danceorientated Asian Dub Foundation.
She's the proud owner of a Mercury Music Prize nomination and a BBC World Music Best Newcomer Award.
Susheela Raman is at the mac Arena from 7.30pm on Saturday - more on macarts.co.uk or call 0121 440 3838.
On Sunday it's back over to Coventry to take in a trio of bands who add the world spice to jazz to a greater or lesser extent.
Start out in Castle Yard at just after noon for good humour and great grooves from the Annie Whitehead Experience. This is down-to-earth modern British jazz of the first order, and because of that the music assimilates African influences - the result of the trombonist/leader's exposure to the music of the South African township exiles in the 70s/80s.
The band includes guest vocalist Carol Grimes in addition to its solid line-up of Jennifer Maidman on guitar, Steve Lodder on keyboards, Liam Genocky on drums and relatively new band member Dudley Philips on bass.
The world influences increase with the next band onto the Castle Yard stage - Soothsayers. This septet led by trumpeter Robin Hopcraft takes as much inspiration from the legendary Nigerian bandleader Fela Kuti as it does from Miles Davis, and also has some Caribbean leanings.
Joining Hopcraft are Adesose Wallace on vocals, Idris Rahman, Phil Sawson and Johnny Philips on guitars, Eustace Williams on bass and Patrick Illingworth on drums.
On after Soothsayers is a solo set by the fabulous guitarist John Etheridge. I wouldn't suggest he's a prime player in the world-jazz argument, but his music has all kinds of influences and really is unclassifiable in the end - file under John Etheridge, I guess.
And now for the real world-jazz treat of the weekend. I got all excited a year or so back when the drummer Trilok Gurtu was set to come to the Drum in Birmingham. That gig had to be cancelled at the last minute, so this appearance, also at the Castle Yard but on Sunday evening, is very warmly welcomed.
I first saw Gurtu at the Adrian Boult Hall over a decade ago filling Colin Walcott's shoes in the pioneering jazz/world fusion outfit called Oregon. Since then I've enjoyed his high-energy performances and exhilarating virtuosity on anything that can be stroked or struck both in acoustic context at mac, and electric form at Womad.
This time he is joined by Carlo Cantini on violin and Jan Osveren on guitar.
World music without a doubt - and jazz too with equal conviction.
All these gigs are part of the Coventry Jazz Festival, which starts tomorrow and runs right through the long weekend, culminating in a performance by another fine world music singer, Egypt's Natacha Atlas on Monday evening. She performs with the Jocelyn Pook Ensemble.
