I really enjoy a lot of Keith Jarrett's work on ECM, and much of it was recorded live. Highlights include: Up For It (the most recent Trio disc), La Scala (solo), Köln Concert (solo), Whisper Not (Trio in Paris, 2-disc), The Cure (Trio, Town Hall, New York), and so many more.
Also on ECM, Pat Metheny Group - Travels is excellent. The new release by the Dave Holland Quintet - Extended Play: Live at Birdland, is a great display of musical fireworks by the best current working band in jazz.
On the Telarc label, Ray Brown - Live at Scullers; beautiful and energetic straight-ahead jazz. Concord released a 2-CD set of 3 LP's from the 80's, featuring Brown's Triple Scoop trio, with guest John Frigo on violin, also very good.
Rush's Exit Stage Left was the soundtrack of my teenage years, although I don't know about the quality of the recording.
