Last year Solarstone's third longplayer put the proverbial torch to perceptions of what an EDM album should be. Through tracks like 'Intravenous', 'The Best Way', 'Electric Love', 'Twisted Wing' and its title track, Richard Mowatt displayed an ever-expanded artistic range. Erasing established genre lines it travelled across previously unmapped musical terrain. Now, a year on, its time to revisit that music. Touchstone's been re-touched!

Crowning Orkidea's '20' album is his new '15th Anniversary' mix of 'Unity'. The track that started it all for him, it set an enormous precedent for his production career and was in effect Finland's first trance release. Having been champed by the proverbial cross-section of DJs on its original release (including Sasha, Tong, Oakenfold, Warren, Seaman and numerous others), its elite legacy lives on with his special 15th Anniversary remix of Unity, which expands the track into a jaw-dropping 10+ minute soundscape.
