I like the first half of 'English Settlement' particularly.
'No Thugs In Our House' and 'Senses Working Overtime' are just brilliant.
The second half is a bit too all-over-the-place, I find.
I think I'll regard 'Black Sea' and 'Skylarking' as XTC's most excellent albums, with '....Wires', '....Settlement' and '.....Lemons' one step behind.
'Fear of Music' is great, but I still prefer 'Remain In Light'.
I've started to get into Costello, but have so far only bought his first three albums, so I think I'll need some more time before I broadcast any preferences on his output.
All are excellent albums.
As for Elvis Costello... His 3rd album, Armed Forces, was one of his best, but I haven't been able to listen to him after Punch The Clock.
Senses Working Overtime was the song that first drew me to English Settlement. Thugs, Ball and Chain, and English Roundabout kept me coming back, but eventually the other songs started drawing me in. Runaways, Jason and The Argonauts, Melt the Guns, Fly on the Wall and several of the others are heavily layered with subtle detail.
I even had an extended version of Down in the Cockpit featuring additional work by an uncredited John Cleese. Unfortunately someone stole my copy of it. Fortunately I still have my 45 of No Thugs In Our House. The cover folds out to make a small theatre and includes "cutouts" of the various charcters in the song. This includes the "insect headed worker wife".
Dog, I'm old.
Time to go listen to Gnarls Barkley and Mars Volta.
Oh, and be on the lookout for a South African band called the Parlatones. They are not available in the United States yet, but they recently signed a deal for Europe, Australia, and Japan.
