Some oldschoolers might label this acidjazz, but it's really more classic jazz than acid. Nothing wrong with that. It's in the groove tradition, but not quite as uptempo as JTQ.
The band is Bob Rockwell (sax), Kjeld Lauritzen (hammond) and Esben Bach (drums). Nice in a jazzy, laid-back style. I think they since long time are well-known on the danish jazzscene, meaning they have a solid, professional sound.
