I couldn't disagree more with your opinion, EZ. Deep Purple put out some great, though underrated, albums after reforming. Perfect Strangers, House of Blue Light ( wanna be radio hit or 2 aside), The Battle Rages On, Come Hell or High Water, are all favorites of mine. The really early stuff up to Burn is better IMO but those are still really enjoyable albums ...Rainbow hasn't done anything worth a damn, other then a few songs, since Richie decided to try and become a hit single machine, prompting RDJ's departure.
Personally, I think Rainbow disbanding was a good idea at that point regardless of the Deep Purple situation..
