Touring in support of last February’s long-awaited mbv LP, Dublin’s My Bloody Valentine have announced a date at the Electric Factory on November 9th, their first Philly show in over 20 years.  The shoegaze pioneers reunited in 2007 to finish work on a third album after disbanding a decade earlier.  With songs that were started prior to the break-up,  mbv comes 21 years after My Bloody Valentine’s previous effort, 1991’s seminal Loveless, which had gone on to influence countless bands from Radiohead to Arc in Round in the years since its release.  Tickets for the XPN Welcomes show go on sale this Friday, September 14th; more information will be available here.  Watch the band perform “Only Shallow” from Loveless below.
