In retrospect I do understand the point about changing musical directions, but the Americana-folk-country influences were right there from the first DS LP. Setting me up was remade as a country song both by Albert Lee (in his solo album in 1978-9 and on E clapton's live album) and Waylon Jennings, in 1983. WoL without the synth part is country song. SFA can be heard as a country ballad and many finger work on various songs bring country in mind (even Freeway flyer...) So if OES has 3 country songs (the bug, when it comes to you and How long) It had become about average, for a DS album.
I think you are right the country influence has always been there, but in my mind it became the over-riding influence on OES when in previous albums it had been more balanced. Yes WoL stripped back is a country song - but on the album it's not stripped back, it's a pop song with an organ hook line that is its' character. And there are other influences on BIA too. For instance, MK talks about listening to a lot of music like reggae when recording the album, in one interview specifically referring to listening to a lot of Ijahman Levi (
http://en.wikipedia.org/wiki/Ijahman_Levi) at the time of recording the album.
I found a really good interview here, of MK being interviewed prior to the release of OES where he talks about the inbetween time between BIA and OES (
http://www.odabasi.net/dsint3.htm). Later in the interview he talks about 'writing proper songs' - to me, conforming to a more rigid framework of songwriting. Perhaps for MK working with his heroes put him into their shadows...just look how much he refers to Chet in that interview.
Jbaent, I think you are right too - OES was probably the first step in MKs career, but I don't think he knew it at this point. Look at this part of the interview where he talks about the possibility of recording the OES tunes withour DS: -
"Oh yeah, I mean, I wouldn't write... if I'd written all those tunes and wanted to record 'em another way I would have done it, I mean no sweat at all, I would have just done it. But I find, I think, with all the other work that I do, hanging around with the Hillbilly thing, with Brendan, people like that, I get plenty of outlets, more than enough for a healthy boy. I'm not looking for anything else at the moment; I mean, certainly I wouldn't be *that* interested in doing solo records - it's more fun in a band anyway. You get all the best jokes. If you're on your own... I just wouldn't like to ride around the world, when it was time to play, with a bunch of hired guns." Ironic really,when you read this in hindsight, but there you go.
So for me, if they'd have cut an album fairly soon after getting back off the BIA tour, the energy that you hear and chemistry between the band at the Mandela would have made its way onto the record. As it is, as dmg identifies, by 1990 MK just seems to have got everything he didn't really want on the OES project. Too much time had passed.
