. Glasgow based duo Happy Meals have spent the last year since the release of their debut Apéro touring the globe, experimenting with new sounds and forms, and are now ready to introduce Fruit Juice.

the use of present perfect with the last year seems strange, last year is past it is finished and have spent the action begins in the past and continues up to now. May be the present perfect is used because their new release has just come out or will come out soon. Can somebody explain me why?
