Hey Sonick, I know Deee-lite were around for the better part of the mid 90s, but were they really that popular once the hype of the first album died down? I know there's a big difference between mainstream 'popular' and music-lover 'popular' so I'm trying to be generous here.
No ill-will against the band and their legacy, but I recall going to many a music store and seeing copies of Infinity Within in the cut-out bins (which is where I got my copy!).
As far as Scissor Sisters lasting as long? They could very well burn out if they have to do such energetic shows as often as they do. Not sure how extensive the US tour is, but they've been gigging all over the UK recently. I wish them the best and who knows...maybe down the road we'll see some collaboration between them and some Deee-liteful One? I know they're said to be working with Kylie.
