The Stalactites: Dark Matters
If you're looking to get your progressive rock fix, The Stalactites' Dark Matters could help you in this department. Made up of Johnny B. (guitar), Rudy Hellio (piano, guitar, programming), and Sophie Hebbelynck (violin), The Stalactites is actually a virtual band; making use of the internet and sending each other recorded files from miles away.
Dark Matters is the second compilation for the group. It was released back in August 2011. Don't expect crazy progressive riffs in here though, the album dwells more on the atmospheric/ambient side, combining hazy guitars with moody violin work and great programming.
