Hi Mats,
I do not really know, which SPARQL endpoint you are querying, but for
the case you tried http://dbtune.org/musicbrainz/sparql
1. you should change
?artist mo:creatorOf ?album
to
?album foaf:maker ?artist
2. you should query with out the ";" at the end of your query.
Good luck ;)
Cheers,
Bob

anyone tell me what's wrong with this query?
