Bla

Bla is the room where Oslo's restless music culture comes to hear something new. Its name is Norwegian for "blue," and it sits in a former factory on the banks of the Akerselva, the river that runs through the city, in the creative Grunerlokka district. Open since 1998, it grew out of the jazz and nu-jazz scene that made Norway one of the most adventurous countries in the music, and it has never stopped treating jazz as a living, mutating form rather than a museum piece. This is a genuine concert club, not a bar with a stage in the corner.

At Brenneriveien 9C, in an industrial courtyard beside the water, Bla is billed as one of the largest clubs of its kind in Scandinavia, with a riverside terrace that comes into its own in the northern summer. Over more than a quarter of a century it has broadened well beyond straight-ahead jazz to programme electronic, hip-hop and cross-genre nights, but its identity is rooted in live, improvised music, and it has launched more Norwegian careers than any other stage in the city. That combination of influence, adventurousness and a real devotion to the players is why we rank it No. 15 among the best live music bars in the world.

A former factory on the river

Bla opened on 28 February 1998 in a converted factory building beside the Akerselva, in Grunerlokka, a former working-class district that was fast becoming the centre of Oslo's cultural life. The setting is a large part of the club's character: brick and iron and low light, a room that wears its industrial past openly, opening onto a terrace right on the river. In its early days the operation was split, with a concert association handling the live programming while a separate outfit ran the bar, an arrangement that underlined how seriously the music was taken from the outset. The riverside location, once purely functional, has become one of the most atmospheric places to hear music in the Nordic capitals.

History and the people behind it

The club was founded by Kjell Einar Karlsen and Martin Revheim, who set out to give Oslo's adventurous jazz musicians a permanent home at exactly the moment Norwegian jazz was beginning to draw international attention. From the start Bla positioned itself at the experimental end of the scene, and it became closely associated with the wave of nu-jazz and genre-blurring acts that put Norwegian music on the map around the turn of the millennium. Over the years its remit widened to take in electronic music, hip-hop and cross-genre programming, but that broadening was an expansion of its founding spirit rather than a departure from it: Bla has always been a place where boundaries are there to be crossed.

What the room is like

Bla is a proper concert club: a sizeable, industrial room built for standing crowds and live sound as much as for seated listening, with the raw character of its factory origins intact. In summer the riverside terrace transforms the experience, letting the crowd spill outdoors along the banks of the Akerselva under the trees, drink in hand, with music drifting out from inside. The atmosphere is unpretentious and nocturnal, the Grunerlokka crowd young and devoted, and the whole place has the feel of somewhere that belongs to its scene rather than to the tourist trail. It is a working music venue first, and it looks and feels like one.

The music and who plays

Bla programmes widely, but live, improvised music is its heart. Alongside jazz it stages electronic, hip-hop and cross-genre nights, and it is known for a devoted following around its weekend and after-hours sessions, including a long-running Sunday tradition that has become part of the city's musical furniture. The booking sensibility treats jazz as something contemporary and evolving, which is exactly why it matters so much to Norway's scene: this is a stage where new acts are made, not just where established ones pass through. In a country that arguably does contemporary jazz better than anywhere, Bla has been the launchpad for a remarkable number of careers, and it remains the first name locals offer when a visitor asks where to hear the music done adventurously.

Why we rank it No. 15

Bla earns its place as the leading live-music room in a Nordic capital that punches far above its weight in contemporary jazz. It ranks below the great international institutions above it because it is less globally famous and its programming is broader, taking in electronic and hip-hop nights alongside the jazz, so the stage shares its calendar with a wider range of music than the pure jazz clubs higher up. But within its scene its influence is outsized, and by the standard this ranking rewards, how central live, improvised music is to the room, it is unimpeachable: this is a genuine concert club devoted to the players. It sits just below Buenos Aires' Bebop Club (No. 14) and in the same conversation as continental Europe's other great jazz rooms, including Berlin's A-Trane (No. 10), as a place where the music is treated as a living art.

Getting in: what to expect

Bla runs a busy, varied calendar, so what you find depends entirely on the night: a ticketed concert by a touring or local act, a club night, or one of its free or low-cost sessions. Some events are seated and some are standing, and the bigger names sell tickets in advance, so it pays to check the programme and book ahead for anything you particularly want to see. In summer, factor in the terrace, which is a draw in its own right. As ever, set times, prices and formats change from night to night given how much the club programmes, so confirm the current listing for the event you are after before you go.

Drinks, food and money

Bla is a bar and concert venue rather than a dining destination, so the focus is on drinks and the music rather than a supper-club menu. Expect a proper bar and, in the warmer months, the riverside terrace as the social centre of the evening. Our $$$ rating reflects Oslo's famously high prices as much as the club itself: Norway is an expensive city for a night out, and a ticket plus drinks adds up accordingly. But for the quality and adventurousness of the programming, and for the setting on the river, it is money well spent, and there are frequently cheaper or free sessions for those who want to sample the room without committing to a headline show.

Who it's for

Bla is for the curious: people who want to hear contemporary jazz and its neighbours played by a scene at the top of its game, in a room with real character and a riverside terrace to match. It suits both dedicated followers of Norwegian music and open-minded visitors happy to be surprised by whatever is on. It is less a bucket-list, book-months-ahead destination than a living local institution, which is precisely its appeal.

The verdict

Bla turned a riverside factory into the beating heart of one of the world's most adventurous jazz scenes, and it has kept that role for more than 25 years by treating the music as something to push forward rather than preserve. It is less internationally famous than the marquee clubs above it, and its programming ranges wider than pure jazz, but as a concert club devoted to live, improvised music it is close to essential. For contemporary jazz in a Nordic capital, there is nowhere better.
