Lindsey has recieved a lot of critical acclaim for both his solo and Mac work. I recall many favorable reviews of Out Of The Cradle back in 1992. Stevie got the majority of commercial success. So each, as David stated, got praise. Just in different forms.
My belief is that Lindsey being a male (and a Libran one too as I speak from experience here) wants his cake and to eat it too. He wants to push boundaries, he wants critical acclaim but he also want commercial success. It's his ego that can't accept he can't have everything. I'm sure Stevie's success in terms of "breaking out" as a solo artist without his help as Strand mentioned only made his feelings worse. The fact is he is well respected in his field and critically successful. It's a shame for him he can't be so commercial but it's never going to happen with the record buying masses stuck in the same arena of always buying the safe, radio friendly albums.
Now just going off subject slightly and going back to the other artists I've mentioned earlier I'm seeing a picture of Lindsey's personality here.
If anybody has listened to David Gilmour's new album "On An Island" they will have noticed a lot of the songs and themes are to do with his domestic bliss, his wife and children. Now, if you listen to Eric Clapton's last album "Back Home" the theme is the same. Both equate Heaven to be the relationship they have with their partners. Both sing about their children and the relationships within the family. Both these guys are in their early 60's. They both have young wives and young children. Both have settled down and after years of living the rock star life are now happy and domesticated. The music is laid back and serene in places. You could even argue the same with Mark Knopfler, again he is in his late 50's with a younger wife and young children too. Although his songs are not about domestic bliss they have a laid back maturity to them. It's almost like they have found peace within themselves, or as Gerald would point out, they have gone boring and mainstream..
So we come to Lindsey. He's into his later 50's, young wife, young kids, so naturally we expect more of the above... But no. His music still has an edge and a manicness which suggests he is yet to settle down. Given his antics on the last tour, grinding, flailing and prancing around onstage and the urgency with some of his newer material it could be argued he is either still in a mid-life crisis and or he still believes he is a young man and refuses to grow up. I think he is to be both applauded and yet criticised for his unique behaviour. He certainly has some demons in there..
