15 Years Later: The Grateful Dead's Final Show
15 Years Later: The Grateful Dead's Final Show

This week on the Billboard 200 albums chart, Disney's "Frozen" soundtrack spent a leisurely 13th week at No. 1, while Lindsey Stirling's "Shatter Me" climbed in at No. 2. A total of five debuts arrives in the top 10, including new efforts from Ray LaMontagne, the Passion collective, Timeflies and Whitechapel.

Outside the top 10, there were a number of movers and shakers -- let's take a closer look at some of them:

-- Jim Gaffigan, "Obsessed" - No. 11 - Thanks to the premiere of Jim Gaffigan's stand-up special "Jim Gaffigan: Obsessed" on Comedy Central, its companion album debuts on the Billboard 200 at No. 11 with 14,000 sold in the week ending May 4, according to Nielsen SoundScan. (A new high in both sales and chart position for the comedian.)

The Comedy Central special premiered on April 27, and garnered 1.1 million viewers, according to Nielsen -- making it Comedy Central's most-watched stand-up special this year.

"Obsessed" -- which also debuts at No. 1 on the Comedy Albums chart -- logs the best sales week for a stand-up comedy album in over two years. The last to sell more in a week was Patrice O'Neal's "Mr. P," which debuted with a handful of copies more (but still a rounded 14,000) in the week ending Feb. 12, 2012. That album was released nearly three months after O'Neal died, on Nov. 29, 2011.

A couple comedy albums since then have earned bigger weeks, but they were non-stand-up efforts that were music-driven: Tenacious D's "Rize of the Fenix," Jimmy Fallon's "Blow Your Pants Off" (both in 2012) and the Lonely Island's "The Wack Album" (2013).

-- Grateful Dead, "Dave's Picks Volume 10: Thelma, Los Angeles, CA - 12/12/69" - No. 17 - The band claims its highest debut with this new archival set, which sees its 12,000 sales start driven entirely by direct-to-consumer sales through the Internet. The album is also the Dead's highest-charting set since "In the Dark" (fueled by its hit "Touch of Grey") peaked at No. 6 on Aug. 22, 1987.

-- Pixies, "Indie Cindy" - No. 23 - The rock band's first studio album since 1991's "Trompe le Monde" instantly gives the veteran act its highest-charting set. The group had previously topped-out at No. 70 with 1990's "Bossanova."

-- Johnnyswim, "Diamonds" - No. 29 - The duo, which includes Amanda Sudano -- the daughter of Donna Summer and Bruce Sudano -- scores its first Billboard 200 entry, starting with 9,000. Johnnyswim had previously logged two entries on the Heatseekers Albums chart in 2012 and last year.

Johnnyswim's debut comes almost exactly 35 years after Donna Summer and Bruce Sudano (with his group Brooklyn Dreams) wrapped a 19-week run on the Billboard Hot 100 with the No. 4-peaking "Heaven Knows." It finished out its chart run on May 19, 1979.

-- Amy Grant, "How Mercy Looks From Here" - No. 109 -- After the album was discounted to $5 at Family Christian stores, it re-enters with a 124 percent gain and its best sales week (3,000) in nearly a year. The album had been absent from the chart since last August.

-- The String Cheese Incident, "Song In My Head" - No. 123 - The group's first new studio album in nine years gives the act its highest-charting set, as it debuts at No. 123, surpassing the No. 147 peak of "Outside Inside" in 2001. The new release also crowns Heatseekers Albums.
 
-- Rush, "Rush" - No. 127 - The rock group's self-titled 1974 debut was reissued on 200-gram vinyl in a lavish box set on April 29. Its return to the chart (3,000) is powered by that vinyl piece, which equates to 77 percent of its sales for the week. The album debuted on the Billboard 200 on Sept. 21, 1974 and eventually rose to a No. 105 peak on Nov. 16 of that year.
