i am really interested to discover the music of the medieval and renaissance periods, i really want to know more about the music before the baroque period. any suggestion of music(flute and recorders), books and recordings?

The Oriel Library has some wonderful early music in its catalogue. This is consort music though, not solo!

Have a look at the Werner Icking Music Archive:

There's a mixture of ensemble and solo material on there.
