Riff Week! After polling nearly 5000 musicians over the preceding few weeks, MusicRadar was both surprised and delighted when our poll to determine the greatest guitar riff of all time appeared on BBC Breakfast and Sky News. Find out which riff clinched the number one spot here.

The Tenori-on Orange from Yamaha arrived in November; the gadget is basically a cheaper version of the Little Boots tech-weapon of choice - but with orange lights. Look out for some video on MusicRadar soon.

November also yet another 2009 supergroup: Them Crooked Vultures. Comprising Josh Homme on vocals and guitar, Dave Grohl on drums and Zep’s John Paul Jones on bass, the band’s super-album was, after those of Chickenfoot (see June) and The Dead Weather (see March), the third of the year to be met with critical acclaim.

Finally for November: Steven Tyler quit Aerosmith. Or did he? A very confusing series of events started when guitarist Joe Perry told the Las Vegas Sun that Tyler had quit Aerosmith “as far as I can tell”. Tyler retorted by appearing on stage at a gig Joe Perry Project gig, telling both Perry and the audience that he was not quitting Aerosmith - only to have Aerosmith’s Joey Kramer and Brad Whitford express their doubts as to a Tyler return.

The whole episode left us all utterly perplexed, and rumours of Lenny Kravitz taking the maybe-vacated mic spot confounded even further…
