yes I am being subjective,when Isay boring.
now I will try and say why its not very interesting,the continual use by lester flatt of his g run,really predictable.
the chord progressions used by Flatt and Scruggs in their tunes in randy lynn rag, flint hillspecial, etc are very similiar,the fact that many of the instrumentals are in the same key.
the fact they play in the same tunings,the fact that they play a lot of their tunes in the same tempo,rarely 6/8. its even worse than the wall to wall irish reel syndrome [irish reel players do play in different modes]
old timey banjo players have more variety in their sound, by using many unusual tunings,each tuning gives a different timbre.
Earl Scruggs was described in one of his books as the Paganini ,of the 5 string banjo.very apt.
