It's probably been discussed on here before but it's been leaked for a while now and I've not read anything.
I think it's a massive progression from the last solo album - a more mature and focused piece of work. The songs "Candylion", "Gyrru Gyrru Gyrru" are brilliant pop tunes but the 14-minute epic album closer "Skylon!" is tremendous and the highlight for me. Bouncing along merrily in a totally un-Gruff way yet without getting remotely tiresome.
Rhys should disband SFA and just work on his solo stuff - his individual output shows him as having more ideas, better execution and a braver concept to songwriting than SFA of late.
