It is impossible for me to work out where this band is based, because its members are Australians and Scandinavians and some of them seem to be living in New York. The musicians also play in other bands and most of them are already well-known on the traditional jazz scene. But when the band Ragstretch comes together, they give brilliant, sparkling, tasteful performances. There are plenty of videos of them for you to explore on YouTube. You could try this version of Panama (played in Copenhagen) for starters:
Also from Britain, seek out the videos of Adrian Cox, or Ben Cummings, or The Graham Hughes Sunshine Kings, or Giacomo Smith, or The Basin Street Brawlers. You will have a pleasant surprise.
And in May 2017 a band called The Ten Bells Rag Band was formed in London. The musicians are relatively young and are inspired by such bands as Tuba Skinny in New Orleans. They play some very pleasant traditional jazz.
Elsewhere, you may find such good young bands as Magic Shook Heads and The Hippocampus Jass Gang in the south of France: their videos are worth watching. And in Buenos Aires, you have the Jazz Friends - a terrific, fluent band, whose range of instruments sometimes includes the 'pinkullo' - a South American flute.
In the North-Eastern corner of Italy we find the young Adovabadan Jazz Band of Treviso playing some very tasteful traditional jazz. For example, click here to see them performing Cake Walking Babies From Home.
In Horten (population 27,000), Norway, a group of beginners aged 35 to 55 got together in 2016, modestly called themselves The Sloppy Jazz Newbies, and by the following year were making good progress and starting to attract gigs. You can hear them tackling Big Chief Battleaxe BY CLICKING HERE.
In the Rhine-Neckar area of Germany, a newly-formed band of energetic and enthusiastic young musicians has shown what can be achieved even with a limited range of instruments. They call themselves Die Selbsthilfe-Gruppe (The Self-Help Group) and you can find examples of their work on YouTube.
In Japan, of course, there is a terrific jazz scene around Tokyo. Most of the musicians are still quite young. For an immediate example, have a look at a video of Over The Waves to see what I mean:
And The Dirty River Dixie Band, founded in Texas and playing a very energetic kind of dixieland music, was able to announce towards the end of 2017 that the average age of its members was under 26.
The Dizzy Birds Jazz Band in Berlin is terrific.
And have a listen to The Old Fashion Jazz Band of Santiago, Chile, by clicking here.
And correspondent Michael Meissner has introduced me to Queen Porter Stomp in Sydney, Australia. Here they are, and you can easily find examples of this fine young band's work on YouTube:
Regular reader Phil in the USA has recommended the Moscow-based young bands The Kickipickles and The Moscow Ragtime Band. You may find their work on YouTube.
Above all, of course, there is great old-time jazz being played by YOUNG people on the streets of New Orleans. They offer hope for the future, because the Internet and visits from overseas musician-tourists are spreading their influence very rapidly.
To see what I mean, even if you can't get to New Orleans, try spending some time visiting the City on YouTube. You will be amazed at the quality of the traditional jazz being produced by instrumentalists mostly under forty years of age; and there are plenty of singers of outstanding ability too.
