You'll find some very good ones. Proprius, which did Jazz at the Pawnshop, is a Swedish record label, for instance. I just know that this particular pressing of DSOTM is considered as good as, if not better than, the best original UK-pressings from Harvest.
Sweden has always had a strong music scene, with very good recording studios and an active home market for music, which was able to support a quality production chain. Sweden was often also the country chosen for pressing of copies for all of Scandianavia, which made it possible to invest in top equipment.
Stockholm was also a very popular destination for jazz musicians from the USA during the 60s/70s, and many very good recordings were made and released in Sweden. (Think of Evans/Zetterlund's Waltz for Debby, for instance).
There are a few Swedish troubadours who recorded actively from the 60s/70s, and who released on particularly the Metronome label. Many of their releases are excellent quality, both recording and vinyl. (Fred Åkerstrøm and Cornelis Vreeswijk are artists to look for).
This release is listening joy, and one doesn't have to know what the words mean:
