AT one time they were arguably the biggest band in the world -- and also one of the reasons critics would argue for the rise of punk rock.

Love 'em or loathe 'em, the impact made by one of Accrington's finest sons, Jon Anderson, and his group Yes cannot be denied. As the band prepare for a UK tour this summer, Yes fans can re-live the glory days once more following the remastering of the first four Yes albums.

But do the albums -- Yes, Time and A Word, The Yes Album and Fragile -- stand up to scrutiny 30 years on? Titles such as Astral Traveller, Yesterday and Today and Perpetual Change hint at the king of prog rock's spiritual leanings.

Anderson's voice soars above the driving bass of Chris Squire while Steve Howe's guitar weaves patterns in the mind.

All four CDs feature bonus tracks and numbers such as Starship Trooper, Roundabout and Heart of the Sunrise remain Yes classics to those day.
