This is quite an interesting debate. I am with the majority on here it's a changing scene, but also like what some have said for the worse.
I myself was a young teen through the two tone period so bands like The Specials, The Selecter, The Beat, Madness and Bad Manners were the favorites of the day for me. Alas my parents wouldnt let me go to the gigs because they would end in trouble because groups like the British Movement and the National front would tag themselves (despite being a reggae sounding, mixed group of people) along and cause mayhem. I only got to see later versions of these's groups live and i tell you it was far better then the studio stuff they produced.
The late 80s and early 90s was another good period of music with the 'Mad for it' Madchester movement of bands like The Inspiral Carpets, The Farm, New Order, Happy Mondays along with other indie bands such as Carter USM, The Frank and Walters and James. Saw a few of them live as well.
The mid nineties saw the Britpop battle between Blur and Oasis along with bands like the Verve.
The 2000s has offered me nothing. Even Glastonbury has lost its appeal.
As an aside the music i like is Jamaican and British Reggae, the early stuff from the 1960s where they would sing and get paid a pittence a very melodic period. I also like stuff life the Mamas and the Papas, Simon and Garfunkel etc. I also like smooth dinner Jazz (listening to that now on Jazz FM), the 1980s electric stuff, a great lover of classical of all kinds from Beethoven to Libera, world music i love bollywood songs. Infact it would have been easy for to let you know what i dont like >> Heavy, Heavy Metal, crap rap and gangster.
A very good question Klambert and as you are a young lad i am glad you would like to see a ska revival i am with 110% of the way.
