I saw them last Sunday at Hammersmith along with three friends and we all thought they gave an excellent musical performance. We were clearly not alone because the ovations that followed many of the songs were something else, rarely have I heard so much extended applause.
Obviously, they aren't young men anymore so you are not going get a performance like the first Yes gig I saw in 1977 (latecomer, I know) but this was a very accomplished performance. The guitar, keyboard duel was great fun. I'm a big Rabin fan, bought his first solo album back in 1978 and even went to a Steve Hillage gig around that time just to see Rabin in support slot, so not bothered whether it is him or Howe on guitar (or both as was once the case) but they do have different styles.
I can confirm that Awaken was bloody awesome.
Anyhoo, ARW are more Yes than the band that calls itself Yes and well worth seeing if you are a Yes fan.
I'm sure they will return to promote their new album and I expect I hope to go and see them again.
