One of the very few intact 2nd Index LPs and probably the best condition. There has not been a copy offered to my recollection in a long time. Unlike a lot of people I think this is the better of the 2. The crude instros on the 1st LP don't do a lot for me (neither do the Bee Gees covers, but they are a little better to my ears).
The Rising Storm is probably $2500-$3 for a pretty nice copy.
IMO the WCPAEB LP on FIFO with cover is the top US garage-ish LP for rarity/legend, unless any more than the 2-3 copies with covers have been found. Bachs is probably #2, 2nd Index, Rationals Fan Club, Arkay IV, Rising Storm, Ones, Mystery Meat, etc
I always thought the first index LP was miles ahead of the 2nd. The condition on the copy offered on eBay was unreal though!
