Groovin' You is a PHENOMENAL band. We hired them to perform at our wedding on September 6th, 2015, after hearing of them from a friend and seeing them perform live once in Boston.... Could not have been happier with their performance. Whether it is Stevie Wonder, Pink, Maroon 5, Katy Perry, Jay-Z, the Beatles, Bon Jovi, or Taylor Swift that you want them to play, they do it all, and they do it really, really, really well.
Not only did they bring an unbelievable amount of energy and fun, they were incredibly accommodating. They learned a ton of Jewish music to play for our Hora, which I believe lasted around 20 minutes. Naturally, we were initially worried about the band's ability to learn music with which they were not previously familiar, but they performed these songs flawlessly. We were so impressed!
They were slightly more expensive than some of the other options out there. HOWEVER, I think a good band is the #1 ingredient to ensure you and all other wedding-goers have a blast. You can try and save a few bucks here or there on decorations, caterer, etc. but I would NOT recommend trying to save on the band. You can't really put a price on the dozens of people coming up to you at your wedding saying how awesome the band is, and how much fun they're having dancing and singing along!
I would recommend Groovin' You 10 times out of 10.
