dj shadow/dj krush: collaborative album

[knifeprty82]

hi,
maybe some of you guys know dj shadow and/or dj krush. i'm way into them right now. now  friends told me, that  DJ Shadow & DJ Krush made a collaborative album once and that it was just mindblowing. but nobody has this album anymore, so i was trying to find it. but i didnt find anything, not even some information about this album. the only one i find is the dj krush single "a whim" with a dj shadow mix on the b-side. but thats not the one they told me about. so my question (if anybody knows) is, does this album exists at all? can anybody confirm that the two made an album together? or is it maybe some unofficial mix from some other guy? i cannot find anything about it... thx fpr your help
