The idea of a concept children's album is probably a bit too difficult to pull off. There aren't many I'm familiar with (John McCutcheon's quartet of seasons-related CDs is an exception). Concept albums for 4-year olds are a little broader generally, and don't always work. (Do you want to listen to 12 songs about addition? Didn't think so.)
On his third family and children's music album, Night Time!, Dan Zanes wisely eschews an explicit "nighttime" conceit for a set of songs that sounds very similar to his other kids' music albums, just a little more... nighttimey. (Yes, I'm a critic and I'm allowed to make up words.) By "nighttimey," I basically mean "mellow and relaxed."
This isn't sleepy-time music -- the leadoff track "Night Owl" with Aimee Mann is all about staying up late. The second track (my favorite on the album) is the jagged sea shanty "Pay Me My Money Down." When I first heard the album, I thought a song mentioning bars and jails was an... atypical choice for a children's music album, but in his liner notes he mentions that it was kids' favorite song when he would play schoolrooms. Go figure. It's a blast.
While all the elements of a Dan Zanes album are there -- the beautiful Spanish duet with Barbara Brousal, the Sandy Girls folk song, Rankin' Don doin' his dancehall thang or whatever his thang is -- there is an element of looseness and relaxation that is emphasized more so on this album than on the other ones. Maybe it's just the subtle hints in the liner notes and pictures, but it's easier to picture this album being made (and listened to) as the sun sets long into the evening. The album's one false note, "What A Wonderful World" with Lou Reed and the Rubi Theater Company, fails precisely because it's the one song that doesn't sound like it just "happened." Aside from that, the concept, loose as it is, works.
As with all of Zanes' albums, the album is probably best for kids ages 3 through 8, but is perfectly OK for infants and grandparents and everyone in between. The CD is available through Zanes' website, online, and in what seems to be an increasing number of offline locations. Highly recommended.
