Went to see Gong + Henge in Liverpool on Saturday. I didn't enjoy Henge so much, but I was definitely in the minority. Gong on the other hand were phenomenal. My mate has previously asked me to go see them a few times but I'm not much of a fan having only listened to Flying Teapot, and although I like it I've never felt the need to investigate further. He recently suggested some songs by the current incarnation plus Master Builder from You and I was converted. The new album (Bright Spirit) is very good, but admittedly I'm approaching with very few preconceptions so if you're a fan of a previous era of the band your viewpoint might be different.
Saw this pairing recently in Bristol. Agree that Henge was the weaker of the two, but the young folks seemed to reall like them.
Next generation Gong were ok and very proficient, but for me, did not compare favourably with the 'classic' 70s incarnations in spirit.
