This video is a recording of Brahms 2nd Piano Concerto presented witha reduced score and my own anlaysis of the work
Scores are available on imslp.org

Corrections:
between bars 100 and 118 several dominant chords are marked without including the slash indicating they are secondary dominants. nearly all these chords are secondary cadential 64 progressions pointing toward the dominant of F major and should be written V7/V or V64/V
