FOR Glaswegian jazz fans, the Rio Café's pop up club is like a week-long dream:

a dark, underground space with low ceilings, cabaret club seating and a rotating line-up of the Jazz Festival's key names jamming on stage.

In just a few days this tiny venue saw sets from MOBO winners Sons of Kemet, Ken Mathieson's Classic Jazz Orchestra, and and award-winning vocalist Niki King.

In his all-time classic novel On The Road, Jack Kerouac wrote about jazz's ability to "raise men's souls to joy".

There's more than a little truth in that: I could have sat all weekend absorbing the smooth sounds of the Late Night resident trio.

Something about being in a traditional-feeling jazz club makes me wish I lived in the Beat era, when places like these were everywhere.

The mesmeric, wandering double bass lines, the audience's quiet appreciation of the band's incredible skill and the coming together of different ages and social groups was completely gripping and unique.

It might lack the smoky authenticity of those fabled underground clubs (nicotine vapour just doesn't lend itself to creating an atmosphere like proper smoke), but the advantage of coming away without that ashtray smell more than makes up for that.

What a shame it is that after the festival ends, it's all gone. The Rio Club is a downright delight and if even I miss it, I can't imagine how proper jazz aficionados feel.

Haste ye back, Rio Club.
