sounds like the audio engineer was just getting the levels on everything,
and it's panned as it was on stage from the audience perspective.
keys on left, guitar on right, the sound really starts to come together about 2 minutes in, about the time the key solo starts.
you can hear blackmore tuning his guitar around 2:44....
he is still just getting settle in..
by 3:27, he's dialed in.
from there on out, it's brutal.
