Local hero, Cal, Wag the dog, Metroland and A shot at glory are the soundtracks you NEED to have, beautiful songs, beautifully played, with many musicians adding his best to the melodies... Lot of MK guitar on them.
The Princess Bride is nice but it's mainly Guy Fletcher playing keyboards and synths, with also many guitar by MK, beautiful too, but too much synths in my opinion.
Last exit to Brooklynn is 98% Guy Fletcher playing synths. Strings, percussion etc etc etc all played by him. In just one song you can hear MK playing guitar, the same song has saxophone, and there is two songs with real violins playing. This score have at least three wonderful tracks (A love idea, Tralala and Finale Last Exit to Brooklynn) but the rest, too much synths.
