This is how I approach weddings.

We normally have three to four different locations where music and sound equipment is required. These being; Ceremony, canapes or pre-drinks, dinner/reception and then the dance floor.
We set up separate music systems for each one of these. In other words, there will be a small low profile system at the ceremony, a medium one at canapes / pre-drinks and a beefy mother of a system for the party stuff later.

When you hire man with music you get the advantage of entertaining your guests with live music at all these different places. Here is an example:
A classy piano act for the ceremony.  Beautiful melodies to welcome everyone to that special wedding.

Pre-drinks or canapes. I developed a super cool guitar looping project for this. It’s elegant and funky and works great on a small stage as a visual and aural center piece. In other words, it is great to look at and great to listen to while you are mingling with guests with glasses of bubbles.
Moving on to the reception . The couple has made their grand entrance and everyone is very chatty. Starters are getting served. I suggest here simply playing some background dinner music in a dj style .

Speeches and then the main course. During dinner I do a really slick and unique multi instrument performance on saxes, flutes and all sorts of little blowing instruments like harmonica, melodica, panpipes and penny whistles – Very entertaining and really wow factor stuff.

Then the opening of the dance floor and off to the DJ set of your life.  Later on I add some live saxes and flute to the mix of  viby modern tunes.

Then we trash the place, put ties around our heads, have sex in the bathrooms and do all the other beautiful things that happen at weddings. Party!
