I while ago I came across this excellent (and well maintained) discography of the works of Brad Mehldau. The link is found below this short excerpt :-
This discography contains the complete recordings of Brad Mehldau in chronological order. The discography is divided in several parts:
1. As a leader / solo
2. As a co-leader / collaborations
3. As a sideman
4. As a guest (appearing on 2-4 tracks)
5. Compilations and soundtracks
6. Original soundtrack recordings
7. Miscellaneous (promotional CDs, etc.)
