Metronomy is one of the most groovy feel good bands I have ever heard. They manage to mix a very modern electro sound with retro vibes and synths and make it sound entirely fresh. If you don't know them you need to add them to your playlist! They also have an amazing style, umm look at this....
They were formed in 1999 and have since made 5 albums:
From wikipedia
The current band consists of Joseph Mount (vocals, keyboards and guitar), Oscar Cash (saxophone, backing vocals, guitars and keyboards), Anna Prior (drums and vocals) and Gbenga Adelekan (bass guitar and vocals).
My personal favourite is The English Riviera, in particular the track called The Bay, for some reason I associate this music with summer vacations and good times:
I also urge you to check out their music videos as they also have a really interesting aesthetic, often mixing modern and retro styles that accurately reflect the music!
Their newest album Summer 08 can be heard on youtube but if you want to support this band it can be bought at this website:
