There's this cool looking organisation called Classic Album Sundays, which organises listening sessions of classic albums on good quality audio equipment.
They are doing a series of showings for Pet Sounds in honour of the 50th anniversary.
I don't have any really high end audio equipment, and have always longed for something like this to be organised for a Beach Boys record, so am quite likely to attend the London showing on Sunday week.
It seems they are also doing several other showings both in Europe and in the States.
