on record

[GoldfishLord]

The meat of the show isn’t always a complete success. The drums are so high in the mix that on the rockier tracks, the kick drum overwhelms everything: where Self-Titled was full of detail, here the colouring is lost in a muddy swamp of noise. That mix means Grace – on record, a fabulous, Tom Petty-esque piece of lazy drivetime rock – becomes a bit of a slog, as does Better Angels. The keyboards are all but inaudible, Mumford’s own guitar feels lost, though his voice – and those lyrics – remains clear and distinct.

Marcus Mumford review – great songs, but no hoedown

O2 Shepherd’s Bush Empire, LondonFor this solo show, Mumford is justified in focusing on his album, one of the year’s best. But the venue and sound do it no favours

1. What's the literal meaning of "on record"?
2. Do "where" and "here" refer to "the rockier tracks"?

1. As the recorded album version sounds. (I don't know what you mean by 'the literal meaning'.)
2. No. 'where' is contrastive, similar in meaning to 'whereas', and 'here' means 'in the show'.

You may be missing that the whole paragraph contrasts the differences between the album versions of the songs and the stage show versions.
