一段话的意思

. 这段看起来有些晕.

The discovery that Haydn’s and Mozart’s symphonies were conducted during their lifetimes by a pianist who played the chords to keep the orchestra together has given rise to early music recordings in which a piano can be heard obtrusively in the foreground, despite evidence indicating that the orchestral piano was virtually inaudible to audiences at eighteenth-century concerts and was dropped as musically unnecessary when a better way to beat time was found.

我知道主干是The discovery has given rise to early music recordings ,但还是弄不明白这整段话的联系.

翻译：关于一位钢琴家在HAYDN和MOZART仍在生时表演他们的交响乐，这位钢琴家使用和音来组织整个管弦乐队的发现表明了在早期音乐录制中，钢琴在前景音乐中是非常突出的。尽管有证据指出，在18世纪音乐会中，管弦乐中的钢琴，因其实际上音色微弱不可被听众听见，在发现了一种更好的打拍子方式时被弃用。

有个别词不太准确，但整个结构我想是对的。
