Galahad
There are several bands using this name:
1) Galahad is one of the major names amongst the British Neo Prog scene for years. Their music blends melodic moods and with heavier parts and the strong vocals are a trademark, over an orchestrated instrumental. The medieval themes are constant on their lyrics. They have evolved to something quite a healthly new view on progressive rock. Fans of IQ, Pallas and Marillion should enjoy their music a lot.
