Just as autumn must follow summer, Senior must follow Junior. Röyksopp's poppy, peppy record from 2009, Junior included guest-star vocalists, bright effects, and catchy melodies; Röyksopp's dreamy, downtempo record from 2010, Senior includes neither vocals nor much in the way of four-four beats. For those who jumped on the Junior bandwagon - and there were a lot of jumpers, since it surpassed all of their earlier records on the charts - the music here will be seen as formless mood music, for better or worse. For those who enjoyed Röyksopp's earlier downbeat material, this might seem more like home, although it has less character and warmth than Melody A.M. or even The Understanding. Much of it is simply a sedate version of Junior; for instance, "The Alcoholic" could have easily been slotted on Junior if vocals were added and its tempo was increased slightly…
Except for one other recording, tenor saxophonist Junior Cook's two Muse albums were his only opportunities to lead his own record dates during the 1962-1987 period. 1979's Good Cookin' (played by a septet including trombonist Slide Hampton, trumpeter Bill Hardman, baritonist Mario Rivera, pianist Albert Dailey, bassist Walter Booker, and drummer Leroy Williams) and 1981's Somethin's Cookin' (a high-quality quartet showcase for Cook with pianist Cedar Walton, bassist Buster Williams, and drummer Billy Higgins) are reissued in full on this single CD, except for four alternate takes from the latter date that were included on Muse's original CD reissue.
