While it is band specific, Great Big Sea has a nice site, the Online Kitchen Party is the Message board and has many sections of things not directly related to the band. Info on New Foundland & Labrador, book disussion and general BS as well. Members can be well veresed in Celtic and Maritime Candaian song and band areas. Not quite the bredth and depth of knowlege as displayed here but woth a peek at
greatbigsea.ca   or greatbigsea.com
