I gather Streetlife is considered one of his more lightweight albums (even by Joel himself, IIRC) but personally I prefer it to 52nd Street as an album let alone a surround mix. As for 52nd Street, IIRC, it didn't sound as discrete to me as The Stranger.
I don't consider Streetlife "lightweight", but I do consider it an early album of his where he is still finding his feet, both with his songwriting and his sound. And it's pretty well-known that he wasn't happy with the degree of control the label put on him with the recording of both that album and "Piano Man". With "Turnstiles" he left LA to record that album at Caribou Studios using Elton John's band with James William Guercio producing. (Would love to hear THOSE tracks!) He was unhappy with the results and went to New York to record the album with his touring band and producing it himself. I think all of those early albums are a progression of him growing as a writer and artist and then truly finding his voice with "The Stranger" with Phil Ramone producing.
Each of those early albums have their charms and their uneven spots. I think "Streetlife" is a stronger album overall than "Piano Man" but gets overlooked because it didn't have any big hits or "big" songs. Nothing from that album gets played on the radio anymore or probably live. But it's a more even album from start to finish than "Piano Man" and his songwriting is really starting to flourish on this album. I much prefer it to "Piano Man" which is basically the title track, Captain Jack, Billy the Kid and a LOT of filler, IMO.
"52nd Street" I hear as an attempt to match "The Stranger" --- maybe the only time in his career he actively tried to repeat himself stylistically -- (it's a jazzier, slicker "The Stranger", IMO) but in many ways I like it more. The big hits on the album have been way overplayed, but "Zanzibar", "Stiletto" and "Rosalinda's Eyes" are 3 of my all-time favorite Joel tracks.
I can't wait for my disc from Japan to arrive. ( I chose slow/cheap shipping, so it will be a few weeks most likely) I hope there are no issues with the disc. I've heard the mix before. Yeah, it's not a revelation of discreetness, but it's a nice, full, modern sounding 5.1 mix.
