My favorite Eric Clapton's album is the 24 nights. I wonder what specifically the 24 nights are? I know some of them, say blues nights or orchestra nights.
The album is a "best of" from the 42 concerts Eric Clapton did at the Royal Albert Hall in those two years. Clapton set a record by playing a run of 24 nights at the London Royal Albert Hall between 5 February and 9 March 1991, following an 18-night run in 1990.
You can check out set lists for each date on this website, including the line-up of the band for each night.
