Listen With Others

I don’t know about you, but I found this one hard!  I am not a particularly fast solver but this one was much nearer to 10 hours than the (perhaps) more typical 3+ hours-ish!  I finished at around 1 a.m. Sunday.

The puzzle contained two clue types.  I’d seen this first clue type once before, I think, and even had a go at writing one or two in the past.  To recall, the clue was in a form such as:

<Definition1, with N letters> +

<Definition2, with N letters> +

<Wordplay for the (N-1) letters that Defs 1 & 2 have in common>

A gentle example appeared at 30d:

See stupid confuse wisest (7)

‘See’ is WITNESS, ‘stupid’ gives WITLESS and the rest of the clue ‘confuse wisest’ is the jumble-based wordplay for WIT.ESS.  Simple, eh?

The other clue type featured a misprint in each definition which had to be removed before solving.  Many of these I found tough, for example:

Raised letter containing leak and joint buckled (7)

I could see from checked letters very early on that this must be KNEEPAD – but why?

At long last I spotted that buckled should become BUCKLER, a protector according to Chambers, then it was PEE ‘N’ in DAK ( a letter), all reversed.  Always hard when two of the pieces of a clue are unknown to you!

Once a few letters started appearing in 5d I had .H.N..ND…… and wondered if it might be CHANSON DE GESTE, the Song Of Roland etc but that soon didn’t fit with other crossers.

OPTION 1: 
What with DJs appearing in various stages at 26ac and, later on, at 11ac, plus the mention of rapper Dr. Dré himself in 29ac, the theme was obvious:  hip-hop.  Given the entry at 5d, it was clearly all based around Peter Spirer’s 1997 hip-hop film documentary Rhyme and Reason  https://www.imdb.com/title/tt0120014/
