Hey Ake,
If you have not done so already, give some of Krall's other albums a try. I found 'Look of Love' to be one of her lessor efforts.
A weird album that I really like is Portishead 'Live at the roseland'. It has some of electronica, but it brings to mind a 'magical' live performance - much like the trinity session. Eva Cassidy is awesome. I plan to buy her cd soon. You might also like Gillian Welch/David Rawlings 'Revival' and 'hell among the yearlings'.
I don't know what album it's on, but Tori Amos's live performance of 'famous blue raincoat' is the best I've heard.
I like 'car wheels on a gravel road', but strangely enough it is one of those albums that sound better on a boombox than a hifi.
