I would like to get Daft Punk's discography from dbpedia, and for each album I would like to show: 1) The title 2) The release year 3) The wikipedia page, so I wrote this query:

PREFIX d: <http://dbpedia.org/ontology/>
PREFIX prop: <http://dbpedia.org/property/>
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX : <http://dbpedia.org/resource/>

SELECT DISTINCT  str(?name) YEAR(?relDate) AS ?relYear ?wiki WHERE {
    ?album a d:Album .
    ?album foaf:name ?name .
    ?album d:artist :Daft_Punk .   
    ?album foaf:isPrimaryTopicOf ?wiki .
    ?album d:releaseDate ?relDate .       
}

ORDER BY ?relDate

Which works, except for the fact that there is one album (Alive 2007) which has 2 different release years (as you can see here), but I would like to show only the earliest of the two. How should I edit my query to make this album appear only once with the first date? Thanks for your answers.
