The go-to source for Grammy showtunes -- Upstart label Sh-K-Boom put out three of the five nominated cast albums

The go-to source for Grammy showtunes

With three of this year’s five nominated cast albums, up start label Sh-K-Boom is becoming the go-to source for showtunes. Noms or not, here are the discs to score.

HAIR Grammy Nominated (2005 Actors’ Fund of America Benefit) This charity concert captures the tribal-rock musical in all its psychedelic glory. Big-voiced American Idol bootee Jennifer Hudson turns in a heart breaking ”Easy to Be Hard.”

Bright Lights, Big City (2005 Studio Cast) Jay McInerney’s coke-fueled ode to the ’80s became an Off Broadway show in 1999, and this updated version — which, thank fully, preserves ”Coma Baby” — proves Odeon is still where it’s at.

Dirty Rotten Scoundrels Grammy Nominated (2005 Original Broadway Cast) To borrow an actual lyric: ?Really classy s—.? Starring Sh-K-Boom cofounder Sherie Rene Scott, and featuring two delicious lounge-lizardy bonus demos from Scoundrels composer David Yazbek.

Altar Boyz (2005 Original Off Broadway Cast) This Bible-beating show suggests what might happen if ‘N Sync found religion: homilies set to house music, faith-fueled rap, and lines like ”Jesus called me on my cell phone.” Word (of God)!

The 25th Annual Putnam County Spelling bee Grammy Nominated (2005 Original Broadway Cast) With clever ditties like ”My Friend, the Dictionary” and ”My Unfortunate Erection,” William Finn’s whimsical musical is as adorable on disc as it is on stage.
