Yes, I loved MUD as a youngster but that gave me a quick idea to make a thread about how many bands have changed in general, or music style, or genre, through their careers. 

It is funny how bands were packaged like boxes of cereal or a toy and if that didn't work, and they were lucky, they got a 2nd chance, and were re-packaged.

For my example I used the band 'MUD' as back in the late 60s they were packaged like a Beatles, flower power, Monkies type of band and somewhere in 1973 they kind of went T-Rex, but that wasn't enough. The next year in '74 they would be re-packaged as glam/rocker/teddy boy, Elvis impersonators lol.... well lets face it, it was a strange genre of music that particularly evolved in the UK and European market at that time. 

The first 2 tracks are quite the sound of the late 60s as they slowly evolved into the morphing Genre (think T-Rex) and then the next year came out of the cocoon with the Glam-Rockerbilly/Teddyboy sound. 

So in Mud's case you can hear and see the changes over the space of 6-7 years. 

'Crazy (1973)

'Tiger Feet' (1974)

(incidentally the B side was the best song of their career ['Mr Bagatelle']) 

And lastly, as its Christmas time their Holiday Hit, 

'Lonely This Christmas' (1974)

In the case of Mud the genre change took them from relatively insignificant chart hits to ultra mega hits which became almost 'anthems' at that time. 

Anyhow, please feel free to post anything you have found with bands that had changed a lot over their careers/ The bands can be any band, prog or not, and they can have more than one change, if that can even happen. 

I think the Danish band Gnags is a very good example if you follow them from their debut album in 1973 and until circa 1983 (after that they pretty much settled on their then style). The changes were clearly for the better.

Obviously the longer a band or artist is making music, the more their sound can change, and even within a relatively short space of time. The Beatles changed their sound considerably. But I guess it’s far rarer for a band to change genre. It definitely does happen though, and can be quite interesting. Almost as interesting as watching the fanatics argue endlessly about which era was best. 😜

(I have to admit, with Ulver, that they really don’t interest me until their Blake album, but I love everything from that point on.)

The kings of genre-changing.

I liked the first album you posted Godag Godag even that it sounded dated - the 2nd song Ulvetid you can hear them pull away from the left overs of the 60s and seem confused as to where they are heading musically. The 3rd video Burhons has a distinctive late 70s feel with the keyboard sound and they seem to be going more rock - then by 1980 Rhytmehans they are getting more like a kind of Ian Dury with a bit of Ska thrown in in style - The last video Fogbaenger i liked they had now changed a a lot and more rounded as a band.  I am now listening to the album Plads Til Begejstring which i like a lot.  

How would you describe their style of music in their latest incarnation? 

Had a good listen tonight and never listened to them before, on purpose of course. 

I can see what you mean about the many facets and sounds of this band. 

I'd say it's very rhythmic first of all. There's some inspiration from reggae and African music, and possibly an echo of new wave too. Plads til Begejstring (1986) is often regarded as their best album, but personally I have X (with Fodgænger as the opening track) and Den Blå Hund (1984) as my favourites.
