We have a tradition here at Theater Dogs, and that is to commemorate the Fourth of July by celebrating the greatest American art form: the musical.

It was an interesting year on Broadway for new musicals. Below are reviews of cast albums for three of them (I passed on Little Mermaid because I love the movie soundtrack from Alan Menken and the late Howard Ashman so much that I don’t really want to hear how Ashman’s brilliance was diluted by someone else attempting to fill his shoes; and I had previously reviewed, and hated, Mel Brooks’ Young Frankenstein and Xanadu). There’s also a classic American musical revival below and a pop album by current Broadway star, Kelli O’Hara.

Passing Strange: The Stew Musical ($18.97, Ghostlight Records)

Recorded live from the Belasco Theatre, this original cast recording captures everything the Bay Area fell in love with when the show had its world premiere at Berkeley Repertory Theatre. Stew’s rock score is alternately rousing and mesmerizing. Brilliantly performed by the cast, this album has the distinction of being the first Broadway cast album to be released online first (you can find it at iTunes). It won’t be released in three dimensions until July 15. Recording live was a stroke of brilliance because the audience reaction fuels the experience of the music, especially during the more humorous songs.

My one complaint is that some of the songs ramble. The repetition grows wearisome on some tracks. But that’s a minor quibble. This is a thoroughly enjoyable listening experience with a you-are-there feel that pulses with energy.

In the Heights ($21.98, Ghostlight Records)

I haven’t seen the show, but one listen to this double-album set convinced me that it would go on to win the Tony Award for best score (for Lin-Manuel Miranda, who also stars) and for best musical. This is joyous music that incorporates rap, hip-hop, salsa, pop and more traditional Broadway sounds for a highly pleasing patchwork of songs. Miranda’s rapping is intelligent and humorous, which will go a long way toward not alienating Broadway audience members who might not care for rap while pleasing those who do.

Favorite tracks include the boffo opening number (”In the Heights”), the catchy “Piragua”, Mandy Gonzalez’s “Breathe” and the beautiful “Champagne” (by Gonzalez and Miranda). The recording quality is superb, and though there are hints of Rent here and there, In the Heights comes across on record as a true original.

A Catered Affair ($19.98, PS Classics)

A fan of composer John Bucchino’s, I was eagerly awaiting the cast album for this modest musical about a Bronx family that works itself into a frenzy over the daughter’s impending wedding (the daughter wants to elope, the mother, perhaps attempting to make up for her less-than-wonderful wedding, wants a blow-out).

The first impression from the album is that Faith Prince is amazing as Aggie, the mother. Her solos, “Our Only Daughter” and “Coney Island,” are superb, as is her duet with Leslie Kritzer as daughter Janey. Kritzer and Matt Cavenaugh as Ralph, the fiancé, shine on the duet “Don’t Ever Stop Saying `I Love You,’” which is the score’s standout song. Jonathan Tunick’s delicate orchestrations are gorgeous, and Bucchino’s songs are more about heart and storytelling than about big Broadway moments.

The jarring element of the album is Harvey Fierstein, who adapted the book from previous scripts by Paddy Chayefsky and Gore Vidal. Fierstein wrote himself a role as Aggie’s brother, Winston, and if you know the cast album of Hairspray, you know that Fierstein is more personality than vocal star. In a big splashy musical comedy, Fierstein is just fine. Here, he sticks out and causes little flinches here and there.

South Pacific: The New Broadway Cast Recording ($18.98, Sony Classical)

Gorgeous, wonderful, inspiring – there’s not much left to say about this fantastic cast recording of the Tony-winning Lincoln Center hit – the first Broadway revival of Rodgers and Hammerstein’s 1949 classic.

Kelli O’Hara is a vibrant, honey-voiced Nellie Forbush, and Paulo Szot, with his gorgeous bass baritone, imbues songs such as “Some Enchanted Evening” and “This Is How It Feels” (cut from the original, now a duet with O’Hara) with commanding, sexy power. Matthew Morrison provides a touching “Younger Than Springtime” and a forthright “You’ve Got to Be Carefully Taught.”

Robert Russell Bennett’s original orchestrations are brilliantly realized by musical director Ted Sperling. I’ll always love the original Mary Martin-Ezio Pinza recording, but this revival disc is a welcome addition to the library.

Wonder in the World, Kelli O’Hara ($16.98, Ghostlight Records)

Speaking of Kelli O’Hara, in addition to starring in a hit show, she has a new solo CD arranged and orchestrated by her Pajama Game co-star Harry Connick Jr. (and produced by longtime Connick collaborator Tracey Freeman). There are a couple show tunes – “Fable” from Light in the Piazza, which O’Hara was in, but she didn’t sing this song, “I Have Dreamed” from The King and I and “Make Someone Happy” from Do Re Mi – but this is mostly a sweet pop album. There are three Connick tunes, including the duet title song, which is fantastic, and some James Taylor (”Fire and Rain”), Don McLean (”And I Love You So”) and Billy Joel (”And So It Goes”). There are also some O’Hara originals: “Here Now” and “I Love You the World.” There’s even a song from O’Hara’s husband, Greg Naughton (”The Sun Went Out”). It’s all pretty great because O’Hara is such a solid singer – effortless and compassionate. She may not be belting about being in love with a wonderful guy here, but she impresses with her skill, charm and warmth.

And can we just give a shout out to Ghostlight Records and PS Classics? If it weren’t for them, we’d be well short of the show tunes we love. Please keep up the good work. Please.
