It's certainly not as good as Stockholm the previous year (but then, what is?) - but it's certainly better than the Montreux disc in the same series.
The band were battling against festival time constraints - and the interesting thing is that Jon Lord was allowed to be the dominant soloist. Or was there a fight for solo space going on: a fixed fight with Ritchie as the loser?
Motivated by the festival setting, Jon's in his aggressive Emerson-esque mode all the way through. Fortunately he hasn't forgotten how to construct a solo - so the pitch-bends and power-chords never sound like mere showing-off. The downside is: it sounds like Ritchie had been struck by inspiration and didn't have a chance to utilise it.
"Wring That Neck": after the initial trade-offs, and Jon's first funky solo, the guitarist brings the volume down, always a sign of interesting things to come. Unfortunately we barely get two minutes of them - a mini-solo and an equally brief stop-time section (where Roger gets his two cents in). Then it's time for Jon's cadenza - initially maintaining the tempo, then zooming off into outer space (his fellow astronauts: Greig, Gershwin and three blind mice, all called Ray by the sound of it!) A Ritchie cadenza might have been brilliant tonight, but it's virtually non-existent: a few familiar licks but before you know it it's Jingle Bells and out.
"Black Night": Gillan's only vocal of the night. The sleeve suggests he had voice troubles, but you'd never guess. It's also the only time we get to hear Ritchie really playing like we know he can.
"Paint It Black": another reminder of Paice's superiority as a soloist. No padding here, no unnecessary repetition or crowd-pleasing stunts (hear that, Ginger and Carl?)
Epic number two, "Mandrake Root" has both soloists at their most evil. But again, Jon and his fuzztone dominate the track: his long solo isn't exactly melodically inventive but it shows Ritchie a thing or two about how to do heaviness. Appropriately, Ritchie soon brings the volume down again: contrast and relief. Trouble is, he can barely get a phrase in edgeways: Jon is still dominant. Ritchie, anxious to reclaim the spotlight, resorts to desperate measures: amplifier wreckage. But it's an own goal: one listens through the guitar noise to the rhythm section...and the organ!
