Mogul Thrash do have that feel about them.
I've mentioned before that I compiled myself a burn of the evolution of brass rock, which expanded to a second disc to take in brass rock/funk. What I (re)discovered is the genre has roots right back to jazz dance - e.g. Louis Jordan and before. It underwent considerable development in the soul and hard r'n'b scene during the 60's (e.g. James Brown, e.g. Musselshoals, BarKays with the Stax and Atlantic labels) and then BST came out with their mix of rock tunes in part jazzed up by mostly jazz musicians. However, Billy Cobham with the Breckers and John Abercrombie etc. had pulled together a brass rock type outfit in the late 60's called Dream - 2nd album appeared in '73, that band evolved into Billy Cobham's Band for his 2nd to 4th solo album, and then the Brecker Brothers band appeared (I suggest influenced by the success of the Scot's Average White Band). Another early variant was Electric Flag who were more a blend of Chess brass with Atlantic Stax brass, behind modern electric blues.
I included a track from Flock's first album on that burn, but with hindsight I am rather surprised to have found the woodwind/brass players of Flock never seemed to take the lead during an instrumental (at least on the evidence of the first album) - whilst all the most reputable brass rock bands made plenty of space. BTW Traffic seemed to have their tunes most commonly covered by brass rockers.
Main-stream jazzers jumped on the bandwagon - e.g. Chase (named after leader Bill Chase) and in the UK the short lived Satisfaction - lead by trad jazzer Mike Cotton. Perhaps after BST and Chicago, the UK band If was the most popular and its lead players had paid their dues in British 60's jazz groups. Brass rock can be still heard in a further developed form, e.g. Canadian band Glueleg, the occasional jazz rock of the Austrian band Extravaganza (their 1996 album Save The Robots, has polled as the best jazz rock of the 90's - sort of Steve Vai sound with jazz chords and a Tower of Power brass backing), and some of the early/middle period albums by Jamarequai always reminded me of sounding like Stevie Wonder with ToP or Chicago backing.
Mentioned it before but the DVD Chicago & Earth Wind & Fire Live At The Greek Theatre, is fun but not to be taken too seriously.
Finally useless fact No.1045367: David Clayton-Thomas the lead singer with BST (from BST album onwards), naturalised Canadian was born in the same town as Julie Andrews: Walton -On-Thames in England where Monty Python filmed the historical part of their famous silly walks sketch.
