1963 BBC sessions not on the official "Live At The BBC" albums, feature fantastic R&B covers and some of their best early originals.

No one, least of all Deep Purple themselves, expected the success of 2013's Now What?! It placed at number one on four European album charts and in the Top Ten of six other countries. It also sold exceptionally well: It was certified Gold in Poland, Germany (where it sold over 100,000), the Czech Republic, and Russia – it was the band's first album to crack the U.K.'s Top 40 charts in 20 years. For InFinite, Deep Purple re-enlisted producer Bob Ezrin. At this point, he is almost a sixth member. This the longest running lineup in their history. InFinite is a heavier and more expansive record than its predecessor, but it's not as consistent. Ian Gillian is in excellent form – still possessing intense expressive power and range, his falsetto remains intact four decades on. Don Airey's organ and keys – so elemental in DP's musical architecture – is physical, atmospheric, and dynamic.

Tom Petersson left Cheap Trick following the George Martin-produced All Shook Up, and the band was somewhat left in a lurch, recording 1982’s One on One largely without a bassist; eventual replacement Jon Brant is on record and on the cover, but he’s obscured by a picture of Rick Nielsen, possibly because the guitarist handled the bulk of the basslines on the LP. In any case, One on One finds Cheap Trick rebounding from Martin with a slick, punchy, AOR record, hemmed in a bit by stiff sequenced rhythms – you can almost feel Bun E. Carlos straining against the metronome – but sparkling in its analog synths and pumped-up guitars.

Jeff Lynne revived Electric Light Orchestra in 2015 – due to legal reasons, they were now called Jeff Lynne's ELO – releasing a comeback album called Alone in the Universe and steadily mounting a return to the road. Several dates happened in 2016, but the tour reached its apex in June 2017, when the group played in front of 60,000 people at London's Wembley Stadium. Released five months after that June 24 gig, Wembley or Bust – which was accompanied by a concert film – features the entirety of the gig, and if it's not heard too closely, it could sometimes be mistaken for an ELO greatest-hits album.
