i did my brief stint with them on stylophone some years ago: that was when they were a sprawling 10 / 12 piece - think they're down to a more manageable 4/5 now!
they were nothing if not absurdly (over) ambitious, resulting in some catastrophically crap live shows, as well as some mindblowingly good ones! their 'farewell' show up in hackney a couple of years ago was quite seriously one of the best gigs i've ever witnessed; transcendent prog / disco / new wave with the aforementioned samba band for the (2 hour) encore. i couldn't believe they actually played for about 4 hours in all. mental!
heard very good things about the new album - hope it actually gets released!
