Using high energy musicians, The Kidz All-Starz perform all the lead and background vocal parts. 4 Kidz by Kidz is unlike the Kidz Bop brand that features adult lead singers and have the children singing only during the chorus. The 4 Kidz by Kidz brand is just that — all chidren´s children’s vocals with no grown-ups allowed. The Hoilday Holiday Tunez CD contains such classics as Jingle Bells, Little Drummer Boy and Frosty the Snowman.
