If you ask me ,which bands were the best at British Punk scene in the late '70s and early '80s?I would answer 'The jam was one of them'.Why?, here are some reasons:

They were one of the most popular groups of the day, achieving eighteen straight Top 40 singles in the UK from their debut in 1977 to their swansong in 1982, including four #1 hits.Along with the Sex Pistols, the Clash, and the Buzzcocks, the Jam had the most impact on pop music.

Launching the career of singer, guitarist, and songwriter Paul Weller, who remains a successful solo artist, the trio was known for its melodic pop songs, distinctly British flavour, and mod image.

And i can recommend these albums:
Jam - All mod con
Jam - Snap
Jam - In the city

In February 2006 Paul Weller received the Lifetime Achievement award at the Brit Awards.
And He released Catch-Flame! his new live album which i highly recommend you to listen.
My favorite Paul Weller album is Wild Wood.But it's sure that every album of him is great and sure worth to listen.
