WHERE Clause With Multiple ANDs

I have a table (tblAttributes) that looks like this:

ID|ReferenceNumber|AttrID|AttrVal
1|1|90|7
1|1|91|8
1|1|92|9
2|1|90|10
2|1|91|11
2|1|92|12

I need to return all the distinct IDs where the combination of AttrID and AttrVal matches multiple criteria for that specific ID.

I have the following:

SELECT DISTINCT(ID)
FROM
((SELECT a.ID
FROM tblAttributes AS a
WHERE a.AttrID = 90 AND a.AttrVal = 7) AS x
INNER JOIN
(SELECT a.ID
FROM tblAttributes AS a
WHERE a.AttrID = 91 AND a.AttrVal = 8) AS y
ON x.ID = y.ID)
