Dimension 5 & Ra New School Goa artists ??
I don't think so.
I'm guessing they are on that list because they released on Suntrip, but they've been around, releasing for quite some time, way before Suntrip existed. I'd say D5 is definitelly part of the "old school". Even that album on Suntrip is a re-release from 1997.
I don't think Ka-sol is a new school Goa project either. I wouldn't classify his sound as Goa, but rather "Forest" scando Psy much like Battle Of The Future Buddhas.
Besides, he's released his music since late 90's whereas "new school Goa" to me is the wave that gained momentum following the minimal trends wich were starting at the turn of the century. That means we're talking about 5-6 year gap between Ka-sol early work and say Filetria's first album that I would consider "new school".
Again, I'm guessing he's put on the list because he released on Suntrip, but he released his music way before Suntrip's existence.
