You just need to use parentheses, like so:
(Album repository at: 7) desc: 'this is a good album'
BTW, it is better to use full words for your method and variable names
-- they are much easier to guess.
I don't know about the context where you want to use this, but maybe
it is a good idea to separate it into two statements:
album := Album repository at: 7.
album description: 'this is a good album'.
