If you're not familiar with RPWL they are a German band that started off as a Pink Floyd tribute band. The Pink Floyd references are certainly here and are on subsequent albums because, after all, that's how they got their start. This band does such a great job in their harmonies where that might be the best parts of each of their albums. As with any group, they have matured over their career and their latest in 2008, 'The RPWL Experience' is their best to date. But, you can start here and will not be disappointed if you're looking for something different in the progressive world of music.
