It's obvious that something is going to happen in the next few days,since Slowdive members Simon Scott, Christian Savill, Nick Chaplin and Rachel Goswell started a countdown on Twitter (see below) as mentioned in listadark. The date when the announcement (?) would take place is this 29th January. High expectations among fans who would give their right arm to see them live for the first time ever, with the chance to listen some of the most beautiful songs ever created, including songs that were never officialy released. It seems that after almost twenty years the moment has arrived: Slowdive returns.
The last time the band played live was in Toronto, on May 21st 1994. It looks like this site will have some work to do adding the new gigs - hopefully ;)
Update (24/01/2014): @slowdiveband published their first Tweet announcing the address of the new official Slowdive website: www.slowdiveofficial.com
Update (28/01/2014): It's official: Slowdive are back
