Yesterday at the Voodoo Music Experience in New Orleans, area resident Ivan Neville joined Particle for an extended stretch during Loose Caboose. As of late the quartet has been expanding to a five piece for portions of many gigs as DJ Logic has been opening shows and then guesting as well. Looking ahead, another significant sit-in could take place on New Years Eve as Buckethead will be opening for the group at New Yorks Irving Plaza (tickets will go on sale this week with some additional details expected soon regarding the evening).
