You would probably use 'in addition' in place of 'also' more of then you would use it in place of 'and'. For example, 'John plays the guitar and piano. In addition, he is a good singer'. You could also word the second sentence, 'Also, he is a good singer.' With 'and' it would most likely be all in one sentence, 'John plays the guitar, piano, and he's a good singer.' Overall, I would say 'in addition' is something you will use much more rarely than 'and'. One last thing, people sometimes use 'Additionally' instead of 'In addition', so that is an option as well. They are interchangeable.
