rewrite rule from apache

[matt91]

I'm new to nginx. I've got it all set up apart from a few rewrite rules I need to add from apache, these are:

RewriteRule ^bg_sound_([^_]*)\.xspf$ /includes/bg_audio_player/bg_sound.php?tributeid=$1
RewriteRule ^elvis$ tributeindex.php?artiste=elvis

rewrite rules seem a little complicated in nginx (or just different), I think I will be able to work my other rules out if somebody could help me with these two.

Thank You, Matt
