My favourite band are The Sisters Of Mercy.
Their an 80's cult rock band from Leeds that celebrated their 30th Anniversary this year! They haven't released a record since the early nineties, but they gig very regularly.
Over the years they've gone through many line-up changes, with only their singer, Andrew Eldritch, and trusty drum-machine, Doctor Avalanche, as permanent members.
Essential tracks:
All of their 3 albums are worth picking up, but the one typically regarded as the best is 1987's
